"Pay what you want. Support charity. Get awesome games."
tl;dr: this is not spam
I'm posting this here because I thought it may interest many among here, plus its nice the fact that you can choose how much to pay, and how much to give to the "Electronic Frontier Foundation" and "Child's play charity". I am not related at all with the Humble organization or any indie developer whatsoever.
This bundle offers 6 indie games which work natively on Linux, Mac and Windows, redeemable on Steam, and if you bought these games separately,
it would cost around $70. Instead, you can set the price you want, and you choose exactly how your purchase is divided: game developers, charity, or the Humble organization.
Games included are Aquaria, Crayon Physics Deluxe, Darwinia, Multiwinia, DEFCON and Uplink.
PS: Although you can even pay 0.01, be a good boy and be fair.
