So the Humble Bundle is a set of 6 games that run on Windows, OS X and Linux. (It started as 5 games but a 6th has been added) You can get all of them for whatever you feel is an acceptable price. You can designate who will get the money you pay – developers, charity or some mix of the two. They are all indie games that would sell for over $80 if you payed full price for each – you can have them for any amount you see fit to pay. But the clock is ticking that there is not a lot of time left.
The games are DRM free and whatever you choose to pay gets them for any or all of the platforms supported. I downloaded all 6 for Win and Lin last night. You can pay via paypal, Amazon or Google Checkout. Here is a list of what is available in the bundle.
