[Team Members] Mike Lester [Project Title] Accelerometer-based auto-leveled projection [Description] 
Several projects have been started to add accelerometer support to the BeagleBoard. This project would involve getting an accelerometer installed and working, perhaps using a trainer board, as well the TI Pico Projector. The orientation data from the accelerometer would be used to rotate, skew, keystone the projected image in order to keep it level and normalized.
