And that seven sided dice in the top post is from www.gamescience.com just in case you were wondering

I found one of those dice on the Ragamuffin & Company stand at Tabletop Scotland. Just lying there looking weird. I was so excited to see one in the wild that Jonathan just gave me it! (www.macguffinandcompany.com)

Dear editor, Why oh why oh why will no-one make a full set of d12 based polyhedrals? With numbers, not Roman numerals or dots. I want a 12 sided d3, D4, d6. I wanted a 12 sided d8, d10, and d20 too. No, I don't know how this is mathematically possible. They can figure it out. Yours, Phil
