Okay, so James already pointed at this one in his Grognardia, but it's worth saying it again. You thought the roleplaying dice looked funny? That they must have magickal origins? They might have. The four-sided die for example is really, really ancient. And I don't mean 1973 with that. I don't even mean it looks like a little pyramid. I do mean the Royal game of Ur. It's a 3600 year old racing game remniscent of backgammon.
On the other hand, maybe it was the first role playing game... ;-)
Just in case you're as amazed as I was, here's some more dice history on the awesome dice blog.
