The folks at Mojang - creators of Minecraft - and the folks at the Humble Bundle site have teamed up for a 100% charity donated "bundle." I use quotes because as of yet you're only getting one game. But there's a catch... they're creating that game right now!
Yep, they're taking one week to create a brand new game, and you can watch the "action" unfold live! All payments will be donated and split up between four seperate charities.
