These are the motorized arrays that I designed to demonstrate the Rightward Pointing Arrow Illusion.

This optical illusion was created by the amazing Kokichi Sugihara, a Japanese mathematician. He has also created other well known illusions such as the “Ambiguous Garage Roof” and the popular “Ambiguous Cylinder Illusion”. Please see video description for more about him and for links to his work.
This build does require some additional items beyond 3D printed parts to function (servos, servo motor controller, etc.).
