Cosmojetz is the last, and final item from the series of five products using the gearbox with a single spinning off-center weight. The idea here is to have an absolutely out of control creature, short circuited, disoriented, but, having a lot of fun in the process. Since the person who created Cosmojetz has severe ADD, perhaps we're dealing with a self-portrait situation here. Cosmojetz is a little hard to wind-up for mechanical/physiological reasons, but it is worth the effort once you see it catapulting itself weightlessly, and fearlessly across your table.
