If you haven't already heard, the third Humble Indie Bundle is here. Starting now, if you purchase the bundle, you will get a pass to play Minecraft for free until August 14th. Pretty cool stuff.
For the three people that still haven't tried Minecraft and are looking to donate to charity, help out indie developers, and pick up five games, this is something you might want to check out. Everything included is DRM-free and you can pay whatever you want, so you really have no excuse not to get all up on this.
