Whenever there's a Humble Indie Bundle, there are usually a number of tricks to go with it. The first was the inclusion of a Minecraft trial, then Steel Storm was added. Now you can get all 5 games from the second HIB as well.

That's Braid, Cortex Command, Machinarium, Osmos and Revenge of the Titans - 4 of which activate on Steam. That's 11 games, all for whatever price you want to pay... well, as long as you pay over the average, which is currently $4.80. If you haven't picked up this bundle yet, then hey, what can I say. Just buy it.
