Being a big fan of music and games I am automatically attracted to the idea of combining the two. AudioSurf Lets you do just that. I had way too much fun last night digging around my music library trying to create the best tracks to race on. But don’t take my word for it: “Audiosurf is a music-adapting puzzle racer where you use your own music to create your own experience. The shape, the speed, and the mood of each ride is determined by the song you choose.”
