Zamor Gun (2009)

The Zamor Gun worked by using two tri-axle connector hubs, one to drive the sphere-pusher, and another to act as a rotating trigger. The trigger wasn't spring loaded to go back into place, in stead there were actually three separate triggers; a trigger-pull would both fire the Zamor Spheres and move the next trigger into place. While the gun technically worked, it wasn't terribly easy to use.
