Here is a simple image stabilizer you can make from things you may already have.

Video acquisition of the 2 cameras simultaneously, at a frequency of 30Hz. At this step, image data are huge: 640 * 480 * 3 bytes * 2 cameras * 30Hz = 55Mb/s transferred on the firewire bus! Because we have the 2d positions of the sticks on the screen, and because we know the position of the cameras in 3 dimensions, we can determine via geometrical algorithms the 3d positions of the sticks. Using a positioning algorithm, we determine if the stick is hitting a drum element. We then compute the sound localization and the volume, depending on the speed.
