"...eight metal towers, two each in heights of 2, 4, 6, and 8 feet. They would be self contained and house all our theatrical gear, most of it from the auto industry: car batteries, headlights, stereo systems and sensors. The sensors were pointed to trigger the lights and sound to turn on or off when a dancer passed. Small control boards were added to achieve a degree of randomness to the dancer/sensor relationship."
"The costumes are shiny silver and white skintight unitards marked by white reflector stripes that augment visibility in the piercing striated lighting of the headlights. The women have a white triangular piece of fabric attached to the inseam of their costumes suggesting a skirt. Bob always differentiates between women and men. In this case they look like a species, both genders present, and out there somewhere in deep space."
