I've improved the hardware, with juggling balls made from retroreflective fabric, and now the system doesn't loose track of the ball easily.
I've also programmed VVVV to render the balls in different colours. In the image, I show the basic set up of the VVVV, with modules designed for input (mouse or Wiimote), saving data for later analysis in MATLAB, and for rendering various elements, including the balls themselves, the height of the ball as a function of time (on the top half of the renderer), and the horizontal position of the balls (bottom half).
Have a look at this video!!
And here is some more data.

| Juggling ball height (top) and horizontal position (bottom) as a function of time. When a different juggling pattern is used, different patterns are evident in the motion capture data. On the left, for example, is an example of plain juggling. In the middle, is mills mess. On the right hand side is the 'figure eight'. |
