I believe there are no libraries dealing with webcams in Ruby. Sucks :(

When I needed to do it, I used CommandCam:
http://batchloaf.wordpress.com/commandcam/ with RMagick. This gave me
a framerate of about 2 FPS. I was going to try and make a C Ruby
extension (basing the code on CommandCam), but never got around to it.
