There was a show on cable a few years back that was based on the Spy-Fi exhibit at the CIA. One segment had Tim Smythe showing off a bungie cord powered sleeve device, and a few other WWW items. It was on either the Discovery Channel, or the History Channel, and was produced by Danny Biederman. I'd like to have a dvd of that show.
Another movie with a sleeve device was "The Adventures of Ford Fairlane" (1990), where he had his holding a S&W .38.
