A harmonograph is an apparatus that uses pendulums to create a geometric image.
A simple, so-called "lateral" harmonograph uses two pendulums to control the movement of a pen relative to a drawing surface.
In this program, I made a harmonograph that creates a random balanced, geometrical, shape each time. Change some values and the colors for fun!
change the height and whatever else to 752, 382. it should make it start in the middle or at least close.
