As one of the most advanced invertebrates or as a delicious appetizer, everyone loves the octopus. This model was spontaneously invented in response to a challenge at a party. With its rotational symmetry this model is a forerunner to the whole origami from space approach.

This fourteen-sided Archimedean solid is one of my favorite shapes, and closely related to the Truncated Octahedron, but easier to fold. One of my first successful polyhedra designs.

Original method for folding the twenty-sided platonic solid from a single rectangular sheet of a 2:1 ratio. My method features good utilization of the paper and optimization for size, a easy and straightforward prefold sequence, and a very secure lock. In general, folding a polyhedron from a 2:1 rectangle is easier than a square and better utilizes the paper. This is because you have more edge relative to area, and you can use something like a Mercator projection for the layout, or a two-hemisphere clamshell arrangement.
