Looking for new or homebrew Darwin's World Mutations!

[Raflar]

Google doesn't seem to be helping me much today. I'm starting a new campaign using Darwin's World and the players have expressed interest in seeing new/different Mutations and Defects. Does anyone know of any Darwin's World Fan Sites (or d20 Gamma World for that matter)

I'm specifically looking for Crunch material not found in the books - Mutations, Defects, New Classes and Prestige Classes, etc... (I'm using Darwin's World 1st edition - Core rulebook, Artifacts of the Ancients, Denizens of Twisted Earth, and Terrors of Twisted Earth in case anyone is wondering)

Thanks.

Also does anyone know the differences between Darwin's World 1st edition and 2nd edition?

Anyone? Anyone at all....
