Only' about 8 hours left though. That's $10 "minimum" too. So you can pay more to help more if you prefer.

Essentially it's a charity bundle where a bunch of developers put their games and other stuff (dev tools, music, etc...) in it to encourage donations and it kept growing in scale. There's even a chess one called "Pawndemonium" in there.
