"We are pleased to announce the release of Tokamak Physics Library Non-Commercial License. http://www.tokamakphysics.com/ " I downloaded the demo. It is so frickin L337 I can't even describe it :D Ok, I could, but I'm too lazy. Anyway, it's really good. Anyone want to look into it? Even better, any of you designers want to figure out what we could use it for? ;) Darryl
