For those that aren't familiar with them, Humble Bundle provides games, books, and other digital offerings to customers. What makes them different is two fold. First, they allow customers to pay whatever amount seen fit for a bundle of games (or books, or comics, or music, or whatever), without any DRM attached. Seriously. Second, the money is divided between Humble Bundle, the developers, and charity, again with the specific amounts being divided up by the customer at the time of purchase.
