For any 360 owners who are into silly things like achievements and avatar awards, try out Xbox Labs. It allows Microsoft to run network tests on your 360 in order to improve the service (or to collect all your personal information as part of their plan to take over the word!!!!!!!!1). For 6 hours of letting them dink around with your 360, you get three 0 gamer score achievements and three avatar awards. The first half hour you have to leave it running continuously, at which point you get the first achievement and avatar award. After that you could leave it running for just a few minutes at a time to contribute to your six hours. Second achievement and award are given at an hour and the last achievement and award are given after six hours. I just left mine running overnight and got all three. Also adds it as another "game" on your 100% achievement list.

Kind of pointless (lab coat avatar award is pretty cool), just figured I'd give the heads up for anyone who cares about that kind of stuff. I think it only runs until sometime around the end of this month
