G4's Attack of the Show unveiled what they're calling the Largest Working Nintendo Controller. The classic NES controller is eight feet wide and only cost them $400 to build. The best part, of course, is that it's fully functional. G4 includes some great instructions on how to go about making your own utterly useless, incredibly difficult to store NES controller, complete with wiring diagrams and lots of pictures. Build your own and do Rick Moranis proud.
