Origami

It is similar to papercraft but has 2 crucial differences: There are no scissors or glue involved. Paper is folded to make cool shapes.

I recently got involved in modular origami at work. Modular origami can be created by using mathematical equations and has limitless possibilities as long as the equations are not broken. Each piece is made up of "modules" or multiple pieces of origami all folded the same way. The pieces fit together using pockets and tabs to form interesting shapes (or an uninteresting cube).

I've created 3 pieces so far: cube, gyroscope, and greater stellated dodecahedron consisting of 6, 12, and 30 modules respectively.

Each module is made from a 4.25" square cut from my daily morning meeting sheet. It's one good way to recycle. I just wish I had more colors....
