The U-Force.

It was for the original Nintendo and sucked balls. It was this thing where you were supposed to be able to punch the air and it would read your hand movements or something.

I have no idea what games it could be used for other than Mike Tyson's Punch Out. I never had one, but I remember reading it was pretty much impossible to even beat Glass Joe with the thing.



I also need to add any wireless controller from 10+ years ago. They were all infrared, so you had to hold one about 12 inches from your Nintendo for it to work and get a constant signal. I had some for my NES and used them for about 7 seconds before I chucked them under my bed.
