Home Again

We were away last week on vacation, visiting family upstate and then spending a few days at home to rest and get caught up on things. Spent a whole week wearing no socks and shoes.  We visited Denis and Sara for Anna’s first birthday party. Everyone in Jeannie’s family made the trip of from NYC. All the grandkids together in one place, a rare event. We all went swimming in Denis’s pool, and Lizzy learned how to do a proper dive off the diving board, which was a big thrill. The next we shuffled off to visit my parents. One highlight was a family picnic for all the cousins on my mum’s side. Another was a trip to the zoo. One evening Jeannie and I took a visit to our old college for a walk around the campus. On the last day we caught up with Martin and Kathleen. Little Charlie is getting big!

OUSA ’09 Pictures

Here are a bunch of pictures from the convention. Get ready, there are a lot of ‘em. First up, a few personal favorites among the many, many models on exhibit.

Seth Friedman’s Blue Bar Pigeon. Perhaps my favorite model this year. I think birds are the new bugs in origami. Over the past few years I’ve seen ever more detailed and more sculptural birds. This is one of the best yet. Pigeons are an animal I know intimately, and this one really captures the essence of the animal. Very moving.

Marc Kirshenbaum’s “Blue Sky”. Marc is known for complex models including insects and musicians, and for his whimsical sense of humor. This year he brought that all together in his “Original Beatle”, a beetle playing a guitar. But to me Blue Sky demonstrates such a simple and fresh approach, and ends up being very evocative, so here it is.

Joseph Wu always does such amazing work. He has just the right sculptural touch to bring a subject to life. Here are some of his pigs and an octopus.

Brian Chan is a virtuoso folder who loves to tackle supercomplex subjects. His work transcends mere technique. Here is the anime heroine Rei.

Michelle’s candy box was selected for this year’s Origami by children exhibit.

Here’s a bunch of photos of my exhibit. I hope you don’t find it too indulgent, but what the heck, it’s my blog.

Every year the girls like to fold Laura Kruskal’s Convention Crown.

Here’s T.J. Norville and I folding my U.F.O for the oversized folding competition. It was awesome fun.

My origami Sphere, inspired by Thelonious Monk. Not too battered after spending a whole day bouncing around my backpack. It’s made from a frog base in a way roughly analogous to the way a Waterbomb comes from its base. I’ve been carrying this idea around with me for a while, but had no idea if it would worked until I tried it, particularly the way the paper goes in around the equator. This also is a proof of concept for the tail and fins for my work-in-progress Zeppelin model. I’m now working on a second, rounder, version of the Sphere with 72 rather than 32 facets.

My Pyramid/Sphinx, spontaneously invented in response to a conversation with John Montroll and Won Park.

Paper Jam, Part I

Another Origami USA annual convention has come on gone. This year was an especially productive weekend and fun time for me. I meant to write a post last week when I was preparing for the convention, but I was too busy and ran out of time. So I’ll rewind a bit.

I’ve been busy folding new models and diagramming the past few weeks. A week ago Friday I had planned to take the day off from work and finish folding a whole bunch of works-in-progress. But I had to go in to the office to manage a group of contractors who are taking over the codebase of a project from another group, a project which I will be overseeing going forward. And as it turns out the codebase is sort of a fixer-upper. So it goes.

I had some good origami time on Sunday, but I had to choose between finishing models and finishing diagrams. I already had completed several new models for my exhibit this year and went back and wet-folded a few others, so I decided to concentrate on the diagrams. (More on the uncompleted models soon, as the they will be completed.) I went thru all the diagrams I had made in the last year -– fourteen in all — and proofread them. A few were mistake-free, several had one or two minor mistakes, several more had a sequence of steps that needed to be redrawn for clarity and/or accuracy. And then the last few — the Moose, Adirondack Chair, and U.F.O. needed to be finished. The ending steps of each of these models are fully three-dimensional so every step requires a new, highly detailed drawing. So that took up all of my free time and late into the night the rest of the week.

Last Thursday there was a happy hour event after work for the people in my group. I was vacillating on whether to go, being tempted to skip it to go home and fold. But there has been alot of turmoil lately in my group, and people will speak the kind of truth after work with a beer in their hand that the won’t in the office in the daytime, so I went along to hang out and encourage my colleagues to have another drink and see if there was anything to learn. The place was way downtown in SoHo, a neighborhood that I haven’t been to in years.

The bar was right across the street from where I used to live way back in 1993-94 with my friend Levitt when the area was pretty sketchy. I was in a third story walk-up loft that have a living space in one half and a studio full of stage lighting equipment in the other, and we were (among other things) working on software to automate the control of the lights thru MIDI. The stairway always smelled like machine oil and your were always light headed when you reached the flat. We suspected poor ventilation and carbon monoxide. The neighborhood changed a lot in the time I was there. There used to be some crack bum sleeping up the block, in a doorway that became an Armani store. Guess he had to find another place. Sometimes there were movie shoots on the streets and was able to grab breakfast on my way to work from a catering cart.  Now the building that where my loft was is no longer there, but a new high-rent luxury apartment is standing in its place.

When I got home that night I was too tired mentally to do any folding, so I went to bed early, which turned out the be a good move. I was able to get all my weekend chores done by midday Friday and had some time to finish preparing my exhibit and tweak some of the models I had. Each year my exhibit gets better and this was the best one yet.

More on the conference itself in part 2…

TV Strikes Back

My television spontaneously stopped working one day last week. They finally stopped broadcasting analog TV. I knew this day was coming for over ten years now, because way back in the 90’s I worked in a place doing R&D into futuristic interactive digital media, and it was on the slate way back then. Still, it had already been delayed more than once, so I never thought they’d actually go thru with it. In fact Jeannie put on Conan just so we could see the Snow Crash at midnight, but it never came. “Ha! See?” I said, but they quietly went dark the next day when no one was watching.

So now if we want to watch real time TV we need a weird little box that doesn’t properly turn off, only goes on “standby” with a sinister red light like the Eye of Sauron. For the most part this doesn’t bother me and I usually just unplug the thing, as I’m not a big fan of TV news, talks shows or watching sports on the tube. In fact, it’s been about two years since I watched much of anything on TV.

But TV has been creeping back into my life in form of internet TV. We’ve been getting into watching streaming shows from Netflix and Hulu. I thought my kids didn’t watch alot of TV until he first time I tried streaming from Netflix and saw a whole stack of Hannah Montana in the recently watched bin. It turns out TV can still be pretty entertaining and a good way to turn off your mind when you don’t have to suffer thru all those ads, and you can watch it whenever you like, which for me means late at night.

First we were getting into the classic 60’s show Star Trek, and worked our way thru about half of season one since coming back from New Mexico in April. Also we were turned on to 30 Rock after seeing it on the flight from Hell on the way back from NM. It’s a smart and wickedly funny sitcom, and always has one Star Wars (or other geek show) reference per episode. We had borrowed The Godfather from Netflix, and because it’s such a long movie, it sat on top of our DVD deck for about six months before we finally had the time to watch it. So then we got The Godfather II, and now that’s been sitting there for four months. One Saturday night not too long ago, we decided we could watch 12 or 13 episodes of 30 Rock in the time it would take to watch the Godfather II, so now we’ve basically burned our way thru 30 Rock. We also watch The Daily Show on Hulu from time to time. Usually catch up on the whole week on a Thursday night. Two minutes of ads per half hour is alot more tolerable than ten or twelve.

So you heard it hear first. This is the golden age of Internet Television, a.k.a. a reasonable value proposition for the viewer. In a few years when it becomes popular in the mainstream it’ll become as loaded up with ads and filler as cable and broadcast TV, and they’ll start charging two or three times for the same thing (like I don’t already pay for an ISP, etc.). And then I’ll have to give up watching TV again or go underground. Ah well, might as well enjoy it while it lasts.

Origami Castle Explorations

And so castles made of sand fall to the sea eventually.

Forget what I said about the nice weather. We had a beautiful weekend but it’s been raining for four days straight now. Also it turns out that that plant in our yard is a mountain laurel, not a rhododendron. Ah well. To top it off there’s been more turmoil at the office the last few weeks, culminating in my boss, a VP of technology, resigning yesterday. And so it goes.

After I designed my origami tower I realized I could combine several towers on one sheet to form a castle. And so I’ve been experimenting in that direction. I came up with a bunch of prototypes with several successful layouts. The first was what I’m now calling the Grand Castle. The idea was to have one large central tower surrounded by a wall with four smaller towers at the corners. Once I started folding it I realized that I would also have a tower in the center of each edge wall, resulting in a total of nine towers. These middle towers would be rectangular rather than square and I would have to work out how to finish them. So I made a second version, called the Armory. It’s a single block of a building with four towers in a square with no central tower. This one seemed promising so I tried a few layouts with different proportions. The third one is called the Classic Castle. It consists of six towers in two groups. In the front is a gatehouse flanked by two small towers. In the back is a keep consisting of a large tower with a hall on each side. In between is a central courtyard.

This seems like maybe the best layout, but a lot of work to fold. So I went with the Armory to do as an exhibit-level model because it’s alot less complicated. Also I found it’s symmetry appealing, and thought it’d easier to finish neatly. Once I began I realized the base itself would make a really nice tessellation.

Now I’m thinking I can combine the castle technology with some ideas from the Origami from Space series to create all kinds of domes and spires, and virtually any kind of architectural structure. I have my plate full for this year, but look for more of this stuffs for the 2010 exhibition.

Origami War Elephant

I’m sure you if you read this blog regularly you’ve been wondering how is that origami War Elephant coming along? Well, I’m pleased to announce here it is!

When I started designing this, Jeannie commented that I was aspiring to Brian Chan (http://chosetec.darkclan.net/origami/) territory. Making models at that level of complexity requires some R&D. I folded quite a number of prototypes, mostly out of larger (15″) foil paper, to work thru the placement and proportion of the tower with respect to the elephant body. The other major issue to solve was what to do with all the pleats that ended up at the edges of the sheet. Some of them were tucked inside, but I was to use the ones near the back to make more complete hind feet. The ones in the front were transformed in into multiple tusks in the spirit of Peter Jackson’s Oliphaunt.

Which is cool because I originally got the idea to design this model after seeing Lord of the Rings, thinking a fantastic Elephant would make a nice complement to my Dragon. The concept and design changed as it developed, but it’s nice that I was able to keep that original detail, and that the insight about the relationship between the castle and the tusks turned out to be correct.

The last issue had to do with thickness of the paper.  It’s easy to make pretty much anything out of foil, which is why it’s good for prototyping, cuz you can just crush it into shape. But for exhibit quality models, I tend to use thicker papers like Wyndstone and Canson, and the layers can add up fast and produce a tendency for the model to spring open. In the past I’ve tended to solve this problem by refining my designs to use the paper tension as a feature just where I want it in the model. But for this subject it just couldn’t be simplified out.

So I ended up wet-folding the model. This has been a technique that has been around for years and alot of complex folders use it. But I’ve resisted up until now, feeling that it’s a bit of a cheat. But it works so fantastically, now I’m a believer! You just dampen the parts of the model that you would crush it were foil, and clamp it in place with a paperclip and wait for it to dry. Then the paper is held in place stiffly in the desired position.

In fact I like it so much I went back and touched up some of my older models with this technique!

The model shown here is folded from a 19″ square of Wyndstone Elephant Hide paper.  Coming soon: new origami galleries!

Catching Up

It’s been a while since I posted so here’s a quick update. I’ve been in the middle of a bunch of things; progress on multiple fronts.

Summer’s here! Summer Fridays are in effect at my office. The kids are counting the days until the end of school. We had a good visit with our friends Seth and Cathy at their new summer house over the long weekend, kayaking and making barbecues. Great time. Thanks!

I replaced the drive gears in my garage door opener, and then had to debug all kinds of fussy settings for travel and balance and torque so the thing would go up and down smoothly without tripping the automatic safety shutoff when it wasn’t supposed to. Looks like it’s pretty much there. Also I took the Mustang out for a good long drive the other day. It sounds kinda rough under 30 MPH, especially when the engine is cold, but once it gets above 50 it’s strong as ever. Strange. I wonder what can be done about it. Once I straighten that out I’ll feel better about getting the bodywork done.

I’ve been slowly getting back into updating my web site, which is long overdue for a major overhaul. As a start a made a new index page, which combines the features of old index and home pages, replacing them both.

I got the horn section for my new song Green Glove recorded and mixed, and I need just one more session to tweak some levels before I’m ready to post the rough mix. I’m also nearly complete my origami War Elephant. I’ve been working on this steadily the last month or so. More on both of these in separate posts soon.

New Song: Green Glove

I’ve been working on a new song called Green Glove. It’s sort of a silly song that I made up last winter when we were painting our house, and a green glove literally fell out of the coat closet and onto my head. I just started spontaneously singing it and we had a good laugh.  Days later I was still singing it, and it seemed like it was a catchy tune so I decided to work on it and record it. The song is on the short side and deliberately repetitive, with one verse and a two-word chorus, in contrast to my last song which was very verbose. I took as the model a song like Steely Dan’s “The Fez”, or maybe some Zappa jazz. But it has a big ol’ piano solo in the middle and a sort of buildup ending and none of the repeats are quite the same.

Also this was something of a departure from my usual way of arranging. In the past I’ve tended to work out the structure of a song to the point where I can sing it the whole way thru and accompany myself on piano, and that gives me the skeleton of the song I can use as a basis for arranging and recording. But for this one the arrangement was more mutable and I did a good amount of experimenting once I started tracking. To some extent this was inevitable because there’s a fair amount of layering going on in the vocals and in the instruments in the second half of the tune. So now I’m almost there. The only thing remaining before the frst rough mix is to lay down the horn section parts.

Green Glove

Once I found my own true love
Beneath a shady apple tree
And while green apples fell on my head from above
She wore a
Green glove green glove
Green glove green glove
Green glove, green glove
Green glove

New Mexico Fotoz

Okay here it is.  We took almost 600 pictures on our trip last month, and from that I distilled four galleries of pictures.  If you follow along with my post describing the trip you can probably figure out where every shot was taken.  Good luck

For those of you who don’t want to look at lots and lots of rocks (Hi Mom!) I posted a few images to give you the flava below.  For everyone else, follow the links.  If you need the password, please let me know.

New Mexico Trip

We recently got back from a trip New Mexico, visiting my brother Jim and his family.  They live in the rugged and storied town of Los Alamos.  It was a great time, good to see them and catch up, and we did some sightseeing and lots of hiking in the north-central part of the state.  I’ve never been to that part of the country before and I must say the landscapes are spectacular.  Very different from California, Nevada or Arizona.  Incredible color palettes between the rocks and sky and vegetation.  Also lots of layers of history and culture, and some really good food to boot.

Despite the fact that you can get to the other side of the world from New York City in just a few hours, there is no real convenient way to get to Los Alamos.  The best you can do is two flights and then a two-hour drive.  So Friday was travel day.  We got up super early but the kids did alright.  Got to the airport.  Stood in line.  Waited.  Flew to Denver.  Waited.  Flew to Albuquerque.  Got a car.  Drove off thru the desert, where things started to get interesting.  Up to Santa Fe and then across the Rio Grande for the climb up to Los Alamos.  Lots of mind-blowing scenery on the way.  Total travel time was just about twelve hours, which the same as it takes to get to India.

One you get there, you get a sense of why it’s so hard to reach, why there are so few roads.  Geography is the crucial factor.  The town is situated on an outcropping of finger-like mesas separated by deep gorges, halfway up a much larger structure — the remains of a supervolcano that erupted 100,000 years ago and is roughly 100 miles in circumference.  The town of course grew out of the Manhattan Project, and most of the houses there were built in the 50’s, and there’s really no new places to build, so it has the feeling of an island.  Alot of houses are hanging right off the edges of the cliffs.  Friday afternoon we took a little walk around their neighborhood, and Sunday we took a longer hike down into the local canyons.  Los Alamos is the only town I’ve ever been to where they give you a combination street map and trail map.

We spent the weekend mainly hanging out at Jim & Una’s house.  There was fresh snow Saturday morning and again on Easter Sunday, although it got considerably warmer both afternoons.  The kids had a great time playing with their cousins. We all built a big tower out of Duplos together.  After a while we thought it was too tall and wobbly so we separated it into two towers.  Which we then connected with a bridge.  Then this grew too unstable and we took the whole thing down and built a massive train track setup that ran from the living room thru the dining room, front hall, side hall and down into the kid’s room, where it turned around. The thing had multiple stations, buildings and vehicles.  It was so big we actually used lego trains to transport legos from one end of the thing to the other.

Friday night we went out to an excellent local restaurant, the Blue Window.  The rest of the weekend Jim made some fantastic dinners.  We also had alot of great southwestern food on the trip, all kinds of burritos other things with red and green chili sauce.

Saturday we went for a swim at the local aquatic center, which was really nice and the kids enjoyed.  We also went to the Bradbury Science Museum, which is a cool public display of the history and continuing research of the Lab.  They have replicas of Little Boy and Fat Man, the first two a-bombs.  I felt kinda like the place needed a Slim Pickens style mechanical rodeo horse in the shape of a bomb that you could ride for a quarter.

Jim works in a part of the lab that has nothing to do with weapons and explosions or reverse-engineering crashed alien spaceships, but rather with genetics and protenomics, as a software developer doing informatics and scientific visualization of data.  Pretty cool stuff.  He showed me a book which he worked on that lists the genomes of various strains of the HIV virus along with the protein sequences they encode, and from that a sort of family tree and history of mutations of the virus.  The purpose of this research is to help other medical researches working on a cure for HIV.  At home he built his own TiVo using a Linux box that looked like a piece of stereo equipment, running a bit of software call mythTV.  We watched a few episodes of the classic 60’s show Star Trek, which I haven’t seen in well over twenty years.  I’d forgotten how good (in a cheesy way) that original series was.

Monday we started touring around the state, mainly hiking and looking at rocks.  In the morning Una took us to meet her horse Whitney in a horse park out on another mesa, and the girls got to go for a ride.  Then we drove up to the rim of the supervolcano and down into the caldera, which is a massive crater miles across, with smaller volcanoes (actually full-sized mountains) dotting the high plain.  Everything was still covered with snow, and we saw a herd of elk off grazing in the distance, a bunch of tiny specks.  On the way down, we drove by a local ski place that looked pretty fun and challenging.

That afternoon we drove down, first to White Rock, where a scenic overlook offers spectacular if a bit scary views for miles in every direction, including into the valley of the Rio Grande (still over a mile above see level at this point).  Then is was on to Bandelier National Monument, home of ancient Pueblo cliff dwellings.  They’re set in a valley canyon like those of Los Alamos, but around the crater a few miles to the southwest.  The cave dwellings were built into to soft rock of the cliffside 500 to 1000 years ago and have been remarkably well preserved and/or restored.  The kids had a blast checking out the and climbing up and down ladders, and we all got a good sense of that life here must have been like in pre-Spanish times.  Una is very knowledgeable out the local geography and history and was a terrific guide.

That evening the train Duplos were replaced by a Rube Goldberg style marble rolling system.

Tuesday Jim and Una were both busy, so they lent us their truck and we struck out on our own.  Our first stop was another area of Bandelier.  This one was right at the bottom of the canyon from town.  It was a hike up and across the on top of a mesa and then back along the cliffside on a narrow snaking trail.  I had Michelle hold my hand pretty much the whole second half of the trip.  This site was much less excavated but perhaps more interesting because in addition to ruins of round villages and a bunch of caves there were some good petroglyphs and the views were spectacular.  Around 11:15 AM we heard a big explosion echo across the countryside.  Una says they blow stuff up at the lab from to time.

Then we drove north a good hour to Ghost Ranch, our main stop of the day. The place is famous for being the site of a famous dinosaur dig in the 1940’s, the discovery of Ceolphysis, a small carnivore.  They had a neat little dinosaur museum and an anthropology museum full of pottery, blankets and arrowheads.  The geography is pretty different up there but also very beautiful. We went for a hike up towards the very improbable-looking Chimney Rock.  Then we drove up the road a piece to this little open-air museum that had a bunch of cool stuff about the geology and the ages of the various layers of multicolored rock.  It turns out this was also right near where Georgia O’Keefe lived and did a lot of paintings, so the were a gallery of her art, including some great semi-abstract landscapes.  The last place for the day was Echo Amphitheatre.  This is a natural rock amphitheatre at the top end of a canyon inlet with really cool echoes.  The kids really loved it.

On way back I got pulled over bogus traffic stop, a blatant trap where the cop claimed I failed to observe a no-passing sign for going around a car making a left in the second lane.  This was on an Indian Reservation, and there were a few weird things about it.  The cop claimed he could bring up my license in his SCMODS, but since he was such a nice guy he wouldn’t write me up for that.  Gee thanks.  As he was going thru his spiel, a wind came up so strong he ran back to his SUV.  At least we got to see some real tumbleweeds rolling by.  He came back with an abbreviated rap, and told me to sign the ticket without explaining it, which I’m pretty sure is not legit.  When I read it later it said sighing it is an admission of guilt and I waive my right to trail, just go ahead send a check.  Hurm.  Well if I signed the other place that would’ve meant I agree to wait in jail at the reservation until a Judge happens to come along.  Yeesh.  Literally highway robbery.

Wednesday the whole lot of us rode on down to Albuquerque.  We checked out a couple more sights on the way.   The first was a place called Tent Rock National Monument, which was another canyon valley, this one full of rocks shaped like Kremlinesque domes and cones.  This one was really in the middle of nowhere and getting there involved a long dirt road.  We stopped for lunch at a casino truckstop diner. Chicken fried steak with green chili.  Yum.  Closer to Albuquerque was Petrogylph National Monument, a series of hillsides of black tumbled rocks full of ancient drawings and carvings.  The edge of town was right at the bottom of the park, and you could look out at the vast sprawl of the town.

After this we checked into our hotel, and old style casita in the heart of the Old Town district.  The place was quaint and cozy with a quiet little courtyard.  Within walking distance was the original 18th century church and town square and bunch of buildings of similar age that are now mostly shops and restaurants.  Also running right thru this neighborhood was the historic Route 66.  We had dinner at a great place.  Most everyone else had steak or other red meat, but I had a red chili pasta that was our of this world.  Also excellent Margaritas.

Thursday we decided to take a drive up the old mining trail in the mountains to the east of town.  One mining museum was closed, although there was a large steam locomotive on display outside.   Another one was very eclectic and featured all kinds of relics from over 100 years ago, including lots of blue glass bottles, as well as large collection of minerals including many grades of turquoise and its ore, and even a giant fossil femur from a Brontotherium, a prehistoric member of the rhinoceros family related to the Baluchitherium.

Then we drove up to Sandia peak, which looks down on the high plain of the Rio Grande valley from an elevation of 12,000 feet.  We got lunch in right up there (green chili burger), with the observation deck view out the window.  We walked around and checked out the various vistas, but it was too cold to stay long.  That evening we walked around the old town some more, buying souvenirs and having another excellent dinner.  This time chili rellenos for me.

Friday morning we got to the airport bright and early and said our goodbyes.  We were a bit concerned because the Weather Channel called for a chance of snow in Denver, where we’d have to make our connection to NYC.  Little did we know it would take us almost 36 hours to finally make it home.

I don’t think I’ve ever experienced such extremes of weather in such a short period of time.  There was snow a few time is in the trip, but since the elevation was so high, it got pretty mild in the day, at least down around five or six thousand feet.  Now today back home summer has come early and it’s 96 degrees out.  Luckily we finished off the bulk of our spring yardwork yesterday so right now I’m inside trying to stay cool until a bit later in the afternoon when the sun isn’t so strong.  My main goal for today is to take my old ’67 Mustang out for a short ride.  I tried last week to turn it over but the battery was dead.  Today the battery is fully charged, so it’s time to give it a try, but it’s so hot out I might not bother.  I’ll let you know what I decide and how it goes.

Coming soon: vacation pictures!
