+A Voronoi tessellation. Periodically zooms in and adds new points.
+The existing points also wander around.
There are a set of control points on the plane, each at the center of
a colored cell. Every pixel within that cell is closer to that cell's
control point than to any other control point. That is what
determines the cell's shapes.
