Legends of Grimrock
This is a great way to support the Indie community, as well as PC gaming in general, and there are some incentives to entice users away from being complete cheapskates. Yes, you could pay as little as a penny for the bundle, but if you spend more than a buck, you'll receive Steam keys.
In addition, you only get access to Legend of Grimrock and Dungeon Defenders if you spend more than the average, which is $6.36 at the time of this writing. Not bad considering the titles would normally run around $140 if purchased separately.
When you purchase a Humble Bundle, you're able to allocate your funds however you wish to developers, charity, and a "Humble Tip," the latter of which goes towards bandwidth and further developing the Humble Bundle program. For micro managers, you can even fine tune your funds allotment to developers of specific titles and the two available charities (EFF and Child's Play).
