PoshFroshVery cool. Incidentally, this could be labelled with two digit numbers in base ten if you labelled it as a d85 thrice, or a d51 five times, etc. This would be a way to get an odd spherical die which still had the numbers on the faces, which I know you prefer. I do like it as is though, I was just pointing that out from a math perspective. Thanks for continuing to push the bounds of dice design.
mctrivia@kryptimus for this one the physics engine is built into the cad software(alibre). I have written my own also it is pretty simple math of you know how to do vector addition. I have also started publishing point clouds for non standard dice here: http://Mctrivia.com/pointcloud/
