you'll need a makey makey connected to three physical targets on one side of a big play area and then the same on the other side the game is to score the most in a certain amount of time
this project is based on a cool game developed by the Tech Museum .. its a game that interfaces the makey makey and a bunch of targets that people run and tag (connected with the makeymakey) on the left team and on the right team. it needs some fixin to get it going correctly
