Wow — Sony just released a new battery-free camera called the "twirl 'n take" camera. It's powered by kinetic energy. I think it's pretty snazzy, and it's especially cute that they made the docking station (for uploading the photos) resemble a flower pot.

You roll it around for 15 seconds for one picture. A little slow, but hey — you never have to worry about running out of batteries!
