There's a new Humble Indie Bundle, #4, so of course we couldn't help but mention it. Contribute what you want for a bundle of up to seven awesome DRM-free games on Windows, Macintosh, and Linux: Shank, Super Meat Boy, NightSky, Jamestown, Bit.Trip Runner, Gratuitous Space Battles, and Cave Story+. You can choose your contribution to go to any split of Developers, Charity, and Humble Tip, the latter of which goes to Humble Bundle Inc. itself.
Give the promo video below a watch as well, as it's pretty darn entertaining in its own right:
