NES Shoe
"I recently went to the Sneaker Pimps convention down in Miami and i came across what seemed to me the most interesting shoe I've ever seen. This shoe is actually a NES Mattel Version molded into a shoe. I happened to speak to the maker of this shoe and he told me that it actually plays the games!!!! He said its the only known video game shoe ever made."

NES Guitar Mod
..."What do you do if no amount of blowing on game cartridges is able to get your NES to boot? Well, if you're a maker and a true guitar hero, you give your favorite system a new life as a rockin' "NES Paul."
