🖥 Swirling Circles

This strange animation is the result of me wondering:

• What if I drew circles at each end of a piston, and that piston moved up and down a fixed point on the screen.
• And then made that piston go up and down.
• Then, what if I made the fixed point the center of a circle, and then drew similar pistons at different angles in that circle.
• And then made all the pistons go "up and down".
• And then rotated the circle of pistons around the axis of that circle.

And then I went down the rabbit hole of "what kind of randomness can I add to this thing?"
