This is the $30 Power-Up Arcade Light Switch Plate from ThinkGeek. It looks like an arcade joystick, but it's not -- it's a light switch. I know -- it was hard for me to grasp at first too. The two buttons make different 'PEW PEW!' sound effects and the actual joystick controls the lights like a regular switch. Alternatively, turn out the lights the same way I do: not paying the electric bill. Come on, all the cool kids junkies are doing it. I'll touch your privates for a fix.
