Hard to believe we're already on the seventh main Humble Indie Bundle, particularly given how many one-offs there have been. Cutting right to the chase, this package includes Snapshot, The Binding of Isaac (and the Wrath of the Lamb DLC), Closure, Indie Game: The Movie, and Shank 2. Those who beat the average contribution amount will also receive Dungeon Defenders (with DLC) plus Legend of Grimrock.
There are also soundtracks for the games, and everything here is available for Windows, Mac, and Linux. I shouldn't need to sell you on this Humble Bundle given the quality of what's included. Here's hoping you bargain hunters don't own all of these titles already.
