Group PacMan
When you take five joysticks, combine them to move one single PacMan, you end up with something called PACK-MAN. The game is played based on the simple rule, majority rules, if three people move their joysticks up and two people move theirs down, then PacMan will move up.
I seriously need to make one of these. I need to order a mouser electronics catalog…ASAP!
