Three sided Dice..

[geoschmo]

Speaking of sphere dice, I found a site selling them. Perfect spheres with the dots on six sides just like a regular six sided die. And they are supposed to work like regular dice where one side always comes up.

Apparently how they work is they are hollow with a cubical cavity inside and a ball bearing. The bearing will always come to rest in one of the corners, causing that side to be down.
