Biggest icosahedron ever?
Some MIT students (I used to be one) built a 20-sided die in honor of Gary Gygax, the recently-dead inventor of Dungeons and Dragons.
Do you know of any physically larger icosahedron? (And, for that matter, how large is this one? I'm guessing maybe eight feet high, but I'm really just making that up. The building behind it is about four stories, but none of the other relevant distances are apparent.)
