Good point about the wind; there -are- wind resistant tripods (at least to up to 25 mph gusts IIRC), but they =cost=. And they are bulky. That's what's so jazz-worthy about this project. you're talking about 6 low cost digital cameras the size of your hand, 6 tripods that any camera could use. One or two USB 2 hubs and the cables to connect it all to a computer. Aside from the reflectors, all you would need would be said computer, and a supply of drapes to cover any reflective items, and you could take this anywhere. Dojo, dance studio, gym, ect (Although you would probably want to throw at least one standard video camera in the mix, just to have a record to keyframe finger and front of the foot motions from). Yoshi, does your program support multithreading?
