Awhile ago I made a mount for my camera, a Sony w120, that attaches to my bike handle bar. The possibility of recording video was motivation enough but I really wanted it to take pictures with. Ideally I would leave it on and it would shoot pictures in time lapse. Like the one below.. still need to figure that bit out.
