I was trying out Google Sets (you give it a few words or phrases, and it tries to find other words or phrases that belong in the set). Being of a geometrical bent, and having already tried Happy, Dopey, Sneezy (it got it exactly right), I entered “icosahedron, octahedron, dodecahedron”. It came back with a very respectible list of polyhedra, including the surprise “teapotahedron”.

The teapot is of course, prevalent throughout computer graphics circles, and even makes a cameo appearance in Toy Story (a factoid which earned me a mention in Rob Fahrni’s weblog). But I had somehow missed the term “teapotahedron”. It is used as part of the joke that the teapot is the long-overlooked sixth Platonic solid.

A little surfing through the Google results turned up Steve Baker’s A Brief History of the Teapot, and Andrew Glassner’s home page.
