Child's Play and the Electronic Frontier Foundation. The bundle included awesome games like the run-away hit World of Goo.
This year they're back at it with the same setup. Pay what you want, get the games DRM-free and cross-platform. This year's bundle includes popular games like Machinarium and Osmos. If you haven't played Osmos on the iPhone or iPad you're missing out. The game is trance-inducing and utterly hypnotic.
