No really. Some of the best Indie games available and you get to pick your price. Again, really.
The Humble Bundle includes World of Goo, Lugaru, Gish, Aquaria and Penumbra Overture. They all run under Windows, Mac and Linux. You can decide where your payment goes – either to the developers, or 2 non-profit organizations (EFF and Child’s Play). Or you can choose to divide the money how you wish.
At the time of writing, they have raised over $300k!
If you have 1 penny you can afford this deal.
