There's 7 free trials from the Creator's Club up on XBox Live for the duration of GDC.
The standouts that I would really like to see more of personally are Jelly Cars and The Dishwasher: Dead Samurai. Frankly if MS can get more indy developpers on this and make the platform very highly available to all 360 owners, this is something that would add a LOT of value to XBox Live. (Hell, making these free to gold subscribers would make a hell of a worthwhile incentive for more people to subscribe as well).
