It seems pretty obvious that this would happen when the camera module hit the market, that someone would make a camera.  The build is still pretty sleek.  This camera was built as part of an advertising contest ( for sprite, duh ) which the builders incorporated very well aside from painting it green with a sprite logo.  It also watermarks the pictures taken with a sprite logo.

The sprite is equipped with a rechargable battery,  an audiable usb speaker (playing a branded click when photos are taken), a camera module, a pi, and python.
