I featured a giant NES controller a while back and the disappointing think was that it did not actually work. Good news is that is someone thought it would be a cool idea to build a giant working NES controller and after 4 weeks there it was.

You can see the actual progress of the controller being made over at spark fun and I am sure that if you are a bit of a electronic whiz you could probably make one yourself as well. Since the controller is so big you need 2 or 3 people to play so it takes multi-player gaming to a whole different fun level.
