Rubber Ball

So, the folks at Sin City are putting on a rubber-only Rubber Ball party at 8x6 on Saturday January 30....I'm pretty stoked for this. Not surprisingly, they've asked me to conjure up a demo/performance type of thing for this....I'm feverishly trying to think up something sexy, creative, and disturbing. Maybe a medical scene? Gimp control scene? Not sure what I should do, and I don't have a lot of time to think something up. Any thoughts?
