The trial version of the Spore Creature Creator was put on a CDROM for some UK gamer mag and now it's all over the intarwebs. And lo is it brilliant. Making critters is easy and insanely addictive. I made some!
This one is Jethro.
And this one is Rodney.
Plus you get little icon-sized doodz if you want.
Oh, and there's video. Here's Jethro doing a dance with little miniature Jethros. My god the full version is gonna be awesome with a capital Awesome.
