I'm at Clemson Univeristy in South Carolina doing a math research job over the summer. One of my professors is interested in origami, and he showed me a book that taught me how to make buckyballs. They're colored in such a way that each vertex has all three colors, and the same colors never touch. You do that with a Hamiltonian cycle, since there are three edges at each vertex.

The problem that I'm working on involves hypercubes (you can make a cube out of two squares. You can make a 4-cube out of two cubes in the same way--that's a hypercube), so I built a model of one.

Neither of them are too fancy (or well-made), but I'm excited to be crafty and mathy all at once. :D
