Marc Canter is, I gather, a famous person. So says Orkut. He mentioned ArtRage, a free graphics program for windows. Holy crap is it good! It's the best drawing program I've seen for a computer EVER. It's got the best, cleanest UI for any program I've seen and it makes the pretty pictures prettier! Gets it! Gets it now!
Update: Ok, I'd like two things more: zoom and an eye drop to pick colors from an existing graphic. Other than that, it's awesome.
