My angles are many,
My sides are not few.
I'm the Dodecahedron,
Who are you?*
The Dodecahedron has a different expression on each face, so he has one for smiling and one for frowning, and so on... to save wear and tear. After all, you could wear a face out if you use it for everything. This version uses emoticons for the emotions.
It's a lot bigger than just a die (see the coin in the picture, a US quarter, 24.16mm dia.), since it isn't meant to be a die, but more a desk ornament. Still, it will roll just fine.
