Gaughan created David Copperfield's flying illusion, which is notable for its graceful motion and unencumbered appearance. Gaughan holds a patent on a method for creating the illusion of flight. Gaughan also created a "one-of-a-kind" prop for Mark Wilson Productions for a National Fire Prevention Week Event. Using a standard golf cart chassis, John and his team created "Snuffy". Snuffy was a "magical" boiler type fire engine that seemed to drive along without any visible driver.
