Let's bust out the controller's measurements: 100cm by 43cm. This elephant-sized NES control pad was created from balsa wood, styrene plastic and foam by deviant artist Eyes5. The artist explains:

There's a nifty used games store that just opened up near me called Gamedeals. I got to know the proprieter pretty well and he asked me to make a big NES controller for his window display. I say, sure no problem, and two weeks later this is the result. And no, it doesn't actually work to play NES games.

Bummer! Make a jumbo NES Zapper, and you'll be forgiven. Brian Ashcraft
