This is a project for me to learn smalltalk. It simulates a game my wife made for a Kindergarten-Carnival party. In a box is one entry hole and at the bottom four exit holes. Within the box are 10 paperboard toiletpaper tubes, aranged as a pyramid. When you throw in a marble, it will fall randomly through this tubes and will eject from one of the exits. The game is to bet from which exit the marble will emerge.
