For scanning an unscannably fidgety subject, a multi-camera setup is the only option. http://www.instructables.com/id/Mult...Scanner/#step0 has one method of doing it, but I've seen it done with webcams and other kinds of cheap cameras that you can network together.

If there were some way to hook multiple Camera modules to one Raspberry Pi it would make this method a boatload easier and cheaper, as it is, the Multi-Pi scanner looks like a wiring nightmare.

(Kinda sad only less than 20 people saw the potential in the IVPort, even though it was a bit expensive for what it does, and the guy running the IGG never marketed the thing very well.)
