Clap on, clap off. The Clapper. The Star Wars Darth Vader Clapper lets you control your lighting not by using the force, but by clapping. It’s as close as we mere humans will come to having Jedi powers. Darth Vader is more than happy to assist you in turning your appliances on and off. Does working with Vader in this way make you a Sith apprentice? I think it does. Welcome to the dark side I guess.
