At a leadership meeting today we were tossing around ideas, and 1 struck me as really interesting and quite possible. The shapes are different games pieces (as has been mentioned millions of times before), and the goal of the game is to sort pieces into different train cars based on their shape. (this train is moving, by the way). To expand on this thought, the human player would control the train by pressing a button that randomly changed the speed of the train.
