Those Ironside die are very cool, same with the shapeways ones!
but how practical are they?
And I have never heard of that SJG game.
I have a number of dice with Japanese/Chinese characters on them but I've never managed to find a D20. Have you seen one?
Hey, just wondering how difficult (and/or expensive) it might be to purchase a few usable normal-sized glass polyhedrals. Some of those that you have are really pretty, IMO.
