anyone played audiosurf? It's like wipeout but with a difference - you give it some music of your choice (MP3, CD, OGG, whatever's your poison) and it generates a racetrack from it... for example, here's one built on Daft Punk's Harder Better Faster... [yt]-N_-9unbk24[/yt] pretty cool game
its a class game like, youtube doesent show it much justice tho. advice: dont play anything too fast - i nearly had a seizure when i was playing the other day. good little steam purchase
