Shack PSA: AudioSurf $2.49 on Steam This Week

AudioSurf (PC), Dylan Fitterer's music-generated puzzle-inspired racer (or is it racing-inspired puzzler?), is on sale on Valve's digital distribution service Steam for a measly $2.49--a 75% price drop for this week only.

"We've introduced a shopping cart to Steam. To celebrate AudioSurf is now just $2.49, this week only. ADD TO CART!" implores the Steam homepage.

AudioSurf takes users' music in a variety of file formats, including MP3 and audio CD, and creates a racetrack based on the song. Racers then collect blocks in sync with the song's rhythm. At that price, it's well worth trying out.
