Max Moswitzer and Magarete Jahrmann of the Ludic Society embedded the classic game pong into a dress and they've called it the Pong Dress.
Implications - That's right, the classic game is actually a fully functioning part of this dress. With a five by seven LED screen integrated in the Pong Dress, the wearer and a friend are able to move the paddles up and down as the ball, a singular pixel, bounces back and forth. To get your old school gaming fix, two retro controllers are plugged in at hip level. What is even more entertaining is the light-up score display on the chest that blinks every time a player scores a goal.
