Plasma Pong is an unfinished video game created by American programmer Steve Taylor when he was attending George Mason University. It is an enhanced version of Atari, Inc.'s Pong where the ball and paddles move through a multicolored substance simulated via fluid dynamics. The game received positive attention, but development was put on hiatus in 2007 after receiving a cease and desist notice from the Pong trademark owner, Atari Interactive.
