Latest project I'm working on for live audio-visual performance is codenamed h4tek, it follows on from the D01234(5) hypercube stuff. This one uses a 24-cell for visual excitement, and makes sounds a bit like this:

(note: brutally edited down from a 30min session, actual live sounds are slower progressing, and massive thanks to andy for his analog drum engine patch which I ripped a lot of the sounds from...)
more demos of this and plenty other stuff in my podcast:
