The organizers of the Humble Bundle sent along a note reminding everyone that the latest bundle, Humble Indie Bundle 6, will be done in less than 7 hours. If you haven't gotten in on the latest pay-what-you-want DRM-free bundle, the window to do so is getting very narrow at this point.
Humble Indie Bundle 6 contains Shatter, Rochard, Torchlight, S.P.A.Z., and Vessel. If you pay more than the average price (currently), you'll also get Dustforce, BIT.TRIP RUNNER, Gratuitous Space Battles, Jamestown, Wizorb, and several game soundtracks.
As of this writing a little over 307,000 bundles have been sold, raking in $1.975 million. Get it while you can at www.humblebundle.com.
