A Useless box (or useless machine) is a novelty device whose sole purpose is to turn itself off; when you flip its switch to the "on" position, a mechanical arm emerges from the box to flip the switch back "off," effectively making it completely useless but often entertaining, originating from designs by MIT's Marvin Minsky
