Today’s Theme: Geometric Origami

Origami is an excellent medium for modeling many geometric shapes, both 2D and 3D. These models can be one-sheet models, but many of them are modular --- made from many folded, and interlocked units. With origami, one can make all of the Platonic Solids (not solid using origami!), and many, many more complex shapes. Tom Hull has invented modules that can be used to construct Buckyballs with hundreds of units, as well as the well-known FIT (Five Intersecting Tetrahedra) model. In this class, he will teach us a model that has interesting repeated embedded shapes. We might also learn patience!

This model starts with an octagon twist, which we then purse, unfold, and pull out a second, smaller octagon twist, which we then purse, unfold, pull out a third octagon twist, and repeat. This is a complex-level model, but a lot of fun to fold!
