OK, here's an example with sound (worse picture quality though - I'll have to check up on how to use iMovie or some other way of combining video with sound).
http://www.df.lth.se/~flash/ControlExplorer%20example2%20w%20sound.mov
So, I made a Nord Modular G2 performance with one slot for each subwindow, controlled via an OSC to MIDI conversion thingie written in ChucK.
Top Left: Magenta is a low rumble, yellow is a saw drone and cyan is a harp-like arpeggio going up and down.
Top Right: A bass thingie, the different colours control variuos FM and filter stuff.
Bottom Left: Drums. The colours change the patterns for kick, rim and snare respectively, a hihat sound is controlled by all combined.
Bottom right: a slow loop of five notes on a fm/ring modulator thingie.
All of these are patched so that if any of the three control values are above zero, the sound fades in to full volume. Then the values (who depend on how close to the center of a circle you are) control filter frequencies, FM magnitudes etc to change timbres and stuff - except the drums where the just control the trigging sequences. I'm attaching the G2 patch I used to make the sounds. I mostly have put three constant level modules that are controlled by the MIDI parameters 29, 30 and 31 that I send from my OS to MIDI converter.

Trackballs are indeed cool. I've been thinking about using some in the past. The idea was to use a microcontroller to decode a few of them. I suppose one can only get USB trackballs these days, which makes the microcontroller route a bit of a hassle compared to using the HID services in desktop OS'es.
Not only can trackballs be used to set values, rotary style, but due to the endless rotary nature they could be used for 'scratching', or advancing time/position in any kind of data set, which I guess is what you are doing here. Unfortunately I can't test the setup you posted, but the video is a nice enough showcase
