Nick De Pirro and Ian Williams prepare a Yokomo YZ-10 Worlds Car for racing on the Circumambulator track. The car has a basic gray and orange paint scheme with an orange zip stripe on the bottom of the chassis cover. De Pirro is wearing a fireproof balaclava, an article of clothing commonly worn by professional race drivers. The pit enclosure functions as a garage space for preparation and repair of cars during performances, and as a secure vault during normal gallery hours.
