Chances are we'll need to create an Android graphics interface module. =
Most of the GPUs are programmed with binary blobs that we'll have no =
hope of getting. However, the interface to Android is fairly standard so =
we should be able to leverage off that.

have to bring it up on my Atmel gear that has LCDs...
