### The Math

Here's the idea of the math.

- Start with several dots around a circle.
- Add many other such circle of dots in different places.
- Draw the boundary between neighboring dots, such that the boundary is equal-distant to the dots. This is called the [ Voronoi diagram ] [ https://en.wikipedia.org/wiki/Voronoi_diagram ].
- Round out the corners of the boundary.
- Now, let these dots rotate around their center.
