supersloshy writes "Last year, 2D Boy, the developers of the popular independent game World of Goo, had a pay-what-you-want birthday sale with curious results. For the next seven days, Wolfire Games is attempting the same kind of sale, but with some new twists. Wolfire Games' Humble Indie Bundle contains five independent games (World of Goo, Aquaria, Gish, Lugaru HD, and Penumbra) with no DRM and they are all cross-platform. In addition to directly supporting the developers of these five games, part of the money also goes to the Electronic Frontier Foundation and the Child's Play Charity. No matter how much you spend, you also get to choose who your money goes to (charity only, developers only, evenly, or custom)."
