Five cool games for any price you name (don't be a jerk), plus you can specify what (if any) portion goes to the EFF and Child's Play! All the games are cross-platform and have downloads for Windows, Linux, and the Mac - AND THERE'S NO DRM.
Also, if they get over a million dollars in donations, they're going to release the source code for three of the games!
So go get it now!
I just found that when I ordered, they are now throwing in a bonus game: Samarost 2!
Snagged it up a few days ago. Well worth some cash and they won't ever see $0.01 donations after paypal fees, so don't be too cheap guys.
