NES Power Pad as Room Decor
The NES Power Pad was a two-sided floor mat game controller -- circa 1988 -- for early generations of the Nintendo Entertainment System. Think "Dance Dance Revolution," but without the engaging technology or widespread popularity. One side of the NES Power Pad had 12 button-style sensors, while the other side had eight. Gameplay was supposed to happen when you stepped on the buttons with your feet, but it reportedly worked better when slapped with your hands. Well, at least it was a start in the dance pad category.
If you have one lying around that never really worked, cut your losses by converting it into a lovely area rug. Don't have one, but still want to incorporate it into your "gamer chic" décor? You may be able to pick one up on eBay for less than $20 [source: Retro Gaming Nation].
