A perpetual motion machine is one that never, ever stops. Ever. That's a pretty long time, if you think about it. Now, a true perpetual motion machine understood as that - with motion that will continue indefinitely - is, sadly, impossible in our universe. Thanks, physics. For now, until something comes along that breaks all the rules of observed physics, we'll have to make do with battery-powered perpetual motion machines. Kinetic Sculptures have the appearance of perpetual motion and still generate all the awe that comes with it. Put one on your desk and it will draw the fascination of passers-by, for good reason. The mesmerizing, swinging, seemingly-endless motion of these toys is capable of holding attention for hours on end. So, while these Kinetic Sculptures aren't true perpetual motion machines, it could be said that they're perpetual fascination machines. You'll feel like watching them forever. Kinetic Sculptures are classic desk toys, splendid office decoration and divine executive gifts. Grab one for your desk, put a couple in the conference room or the lobby. They're an attractive addition to any workplace.
