The bundle includes Bit.Trip Runner, Greed Corp, Hamlet, Leave Home, Conquest of Elysium 3 and They Breathe. Mac and Linux downloads are also available for Bit.Trip Runner and Conquest of Elysium 3.
As of this writing, the bundle is still under $5, though the price goes up as more people buy. Those who pay at least $8 also get a download of the jazzy chiptune album Bluescreen by Protodome. Not a bad deal, especially if you've misplaced the copy of Bit.Trip Runner you got with the last indie bundle you purchased.
