d120 and d48 Dice!
I collect dice, just started with my return to RPG Gaming. Just larking around online looking for dice and this turned up!
Absolutely and utterly useless in gaming, but to a collector, really frigging neat! Wish Gamescience would re-release the Zoccihedron (d100) at a sane price, since just FINDING one on eBay is rare, and the price is always astronomical.
Dice Lab also offers a d60. I can see more dice strangeness in my future.
