Has anyone interested in Polybius ever seen the movie "Strange Brew"? Part of the plot involves a beer company putting an arcade game in the cafeteria. When guys play the game, they become hypnotized. Then the company uses music (an organ) as the mind control device to get them to play hockey death mactches against each other (and their all dressed up like Star Wars storm-troopers when they play). It's actually a pretty funny movie, and a good movie example of using an arcade machine to affect people's minds.
