Someone asked how I move the GoPro camera when it's in time lapse mode, so I made this behind the scenes video. (Link to YouTube) My home-built device uses two kitchen timers, one for tilt and the other for pan. The system is modular, so it can be configured for movement in any direction or combination of directions.
By the way, here's the little demo I'm doing in the video, painting two plaster heads in casein.

IKEA kitchen timer (pan move)
