A Mathematica demo I made of wandering around a parameter space of the convex hull of various scalings the vertices of a icosahedron, dodecahedron, and icosidodecahedron.

Given the right parameters, we can recover all Platonic and Catalan solids with full icosahedral symmetry.

Just this past month, I've been working with Pontus von Brömssen and Bert Dobbelaere on analogous problems for other space-filling polyhedra. Here are all of the ways of placing 4 cells (each 1/12 of a rhombic dodecahedron) of the rhombic pyramidal honeycomb face-to-face.

We played GoL with wraparound—so I showed them why we call this a torus too!

I'm a faculty member at "Camp Conway" this week and I was asked to give a talk during the morning session.

Of course, every student who goes to Camp Conway should come home knowing a little bit about Conway's Game of Life, so I made Conway's GoL starting with initial conditions of Conway.

Next step: buy a 3D printer and print a puzzle!
