Ever wondered what a cross between Torus Trooper (on the site), Tetris and Guitar Hero would be like? Me either, but it turns out we don't have to - somebody already did it for us!
Audiosurf takes music tracks (mp3, ogg, m4a, cd audio, FLAC, etc) and turns them into tracks on which the game takes place. High bpm tracks produce intense games at high speed (and with high scores), gentler ones are far less intense. It uploads your scores when you finish a track and lets you compare them against other users who played the same song (and it emails you if somebody knocks you off the top spot for something), in a nice competition-breeding fashion. There's a selection of different characters who each have their own play styles (and more are apparently promised). Plus if you get it on Steam for a measly $10 - there's a demo on the site to try first - you get the Orange Box soundtrack thrown in, including a couple of versions of Still Alive, and Steam community achievements to go for. I've been playing it a lot last night and this morning, and it's great. Especially recommended are drum&bass tracks (Pendulum are very popular), long rambling metal (people seem to be playing Dragonforce rather a lot - despite the cheesiness

There's a bunch of videos on YouTube if you want to see it in action - this one's pretty good.
