You can now buy the new Humble Indie Bundle 4, a two-week deal that includes five games (Super Meat Boy, Shank, Bit.Trip Runner, Jamestown, and NightSky HD) for whatever price you'd like. The more evil-hearted of you may be thinking of grabbing the games for one cent, but before you do, keep in mind that the proceeds will go — by default — 65 percent to the developers, 20 percent to charity, and 15 percent to Humble Bundle. You can customize those percentages and choose between the American Red Cross and Child's Play charities, and to sweeten the deal even more, you'll get Gratuitous Space Battles and Cave Story+ for free if you spend more than the average price ($5.32 at the time of writing). All of the games work on Windows, Mac, and Linux, are DRM-free, and you can redeem them on Steam if you so choose.

Update, 12/20:  The bundle's even more irresistible today, as now those paying over the average ($5.15) get And Yet It Moves, VVVVVV, Cogs, Crayon Physics Deluxe and Hammerfight as part of the deal!
