Like the original (shown below), the new and improved “Most Useless Machine” doesn’t serve any purpose. But play with it (or duel with it) for a moment and you realize that it is a cleverly designed toy. Push the switch and so starts the duel between man and machine. The box opens and then closes by turning itself “off”. The open and close game goes on for a bit, but then the box shuts, runs away, and goes into a frenzy (sliding, spinning, and rolling) before shutting down for good!
