The latest Humble Bundle for Android has been kicked off, and includes a bunch of exceptional games. Splice, Eufloria, Waking Mars, Crayon Physics Deluxe, and an early Android beta for the excellent Superbrothers: Sword & Sorcery are all available. If you pay more than the average (currently $8.89) you also get Machinarium.
You get to pay whatever you want for these, and the money is split up between developers, the Humble Bundle organizers, and charities like the Electronic Frontier Foundation and Child's Play as you see fit. Every signle one comes with the original soundtrack, and is available on Windows, Linux, and Mac PCs.
A lot of these games aren't in Google Play, so, go get the bundle! It's a great deal, and for a good cause. Hey, if you're in the charitable mood, why not contribute to the MO-bile Nations Movember run? We're raising money for men's health by sprouting exceptionally poor facial hair. Seriously, I don't know how I'm going to go out in public like this.
