“Ever wanted to control your TV with an old school Nintendo controller? No? Well, I have and now I do. A few weeks ago I picked up an old school Nintendo controller from eBay and began thinking of a project for it – then it hit me! Controlling the basic functions of my TV through a NES pad would not only be awesome, but it would make me one step closer to that darned Captain-N.”
I think that’s a way better use for it than as an optical mouse (via /.).
