Met him at GenCon UK in the 1990s. His Doc-From-Back-To-The-Future energy was absolutely mesmeric. He had five towers of D10s in a plastic tubes. Three towers was the standard dice we all had in our bags and two were towers of his Game Science d10s. The standard dice towers all had different heights but the two game science towers were identical heights. He explained that for the regular dice, the smoothing process (which made them nice to hold!) changed the shape enough that they weren't regular sized anymore. The Game Science dice weren't smooth (sharp edged) and so they kept their shape. Of course, if you want a die to roll fairly, it needs to be a regular shape.

I bought a Zocchihedron cos we were playing a game that used percentages (Icar RPG) but rolling it was hilariously haphazard as it was essentially a ball! Loved it tho. I later received the game science dice set as a gift, which I still have. Sadly little time to play these days.
