Can't really say that I simply liked that ..... but can certainly say that I positively LOVED it!!!
I'd guess there must be some adjustment of the flyball governor available in order to control the speed, which would be visually determined by the removeable graphic centerpiece that was setting on the record at first, and off on the side at the end. Probably was printed with a proper spacing to "stall" the motion of the "spokes" when running at the correct speed.
That is soooooooooooooooooooooooo COOL!!!
