Five-Banded Armadillo  2007

I had a close encounter with a family of these cute creatures on a vacation in Florida. They were living under the hot tub of the house we were renting and could often be seen shuffling around the yard. This model uses my hex base and features a detailed shell, claws and head. The hardest part of this model was making the ears without developing any new points, and without sacrificing the closed back. Fun fact: a group of Armadillos is called a fez.

Hot Air Balloon  2007

Complete with a gondola, this model extends the Origami From Space approach to terrestrial curvy flying objects. A stand can be made from an Easter egg dipper or the wire cage from a champagne bottle. Placing a marble or small stone in the basket will give it weight to keep it stable in the stand.

Icosahedral Slices (Tri-Pent Polyhedra)  2001

I discovered an interesting shape: an octahedron made of three regular pentagons and five equilateral triangles. I've never seen this shape before and don't know if it has a name, so I'm calling it the Tri-Pent Octahedron. It has the interesting property that if you replace each pentagon with five equilateral triangles you get an icosahedron. Several other shapes have this property, including the pentagonal antiprism and a pentagonal pyramid. There's another shape with 15 triangles and one pentagon, and yet another still with two pentagons and 10 triangles, but it's not an antiprism because the pentagons are not in parallel planes. Here are CP's for the complete set of shapes "Icosahedra with One or More Slices Cut Out of Them, Whose Faces are Composed of Pentagons and Triangles."
