The San Francisco based charity Umloud is holding an eBay auction that gives the high bidder and four of their friends a chance to get a private preview of Kinect Party (the upcoming sequel to Double Fine Happy Action Theater) and to play the game with Tim Schafer himself! At the time of this writing there is less than an hour to go. But at a current bid of only $355 USD, this is a steal!
I'd totally bid myself if I had the money and lived on the correct side of the United States. If you are lucky enough to have those two important qualities that I lack, then bid now.
