The crazy man shown above approached me while I was attending Joe McNally's class at the Lepp Institute. He had no fewer than *twelve* flash units all being triggered using TTL via radio poppers. Using this setup, we were able to shoot using high speed sync at 1/8000 of a second and turn daylight into night time. Go check out Syl's blog for more info on the setup and to see what it looked like when shooting from the other side of the flashes.
