its a double pendulum with some funky square action
i think i counted the yellow square making 26 revolutions....
Gee, I wonder what happens to the holey foundational pillars of modern "science" when somebody decides to install a vector biased centrifugal clutch at the pivot which connects the two squares, such that when the outermost square hits the rpm sweet spot, it delivers it's kinetic payload to the relative periphery of the system...
