As far as incredibly ambitious --almost magical-- controllers go, nobody could ever fault the infamous PowerGlove by Mattel for the Nintendo Entertainment System. This was a suitably futuristic glove, a high-tech gadget that should have cost thousands of dollars and it would allow you to control your NES games via gestures.
Of course, it didn't really, though it did come relatively close considering the era and the asking price.
Now, the Power Glove may have never really worked properly, but it remains both iconic and collectible. What's more, you can grab it complete in its box via this PowerGlove (NES) auction on eBay. Its size is large, mind you.
