Technomancy

I'd like to make a helmet camera. This would be a camera that's attached to the top of my motorcycle camera, and records what I see. Recently I went on a motorbike trip and I saw some lovely scenery, however I couldn't take any photos because I was riding my motorbike. A helmet camera would be great for this. It could also be used for mapping in OpenStreetMap. I could drive around with this recording video and then use screenshots to map features in OpenStreetMap. Someone suggested a Sanyo Xacti camera as a simple little camera I could get on eBay that I could take apart.
