Crayon Physics designer Petri Purho just posted some art from an unnamed seven-day game he's working on (as in, created in seven days, according to Experimental Gameplay Project rules), a shoot 'em up using procedurally generated graphics and creatures. Click on the images for higher rez versions.

"It's probably going to be a SHMUP and hopefully it's going to be out soon," Purho emailed. "It might also end up being a part of something bigger that involves other people as well, but I can't talk about it right now, since that's hush hush. :)"

OK, so collaborating with other people is a flagrant contravention of Experimental Gameplay Project rules, and you probably won't see this one in GameStop any time soon (unless Purho adds another leg to his characters, and maybe the Mr. Men license), but hey, we like Petri Purho. We've marked June 4th on our calendar -- it better be done by then!
