  50 A Voronoi tessellation.  Periodically zooms in and adds new points.
  51 The existing points also wander around.
  52
  53 There are a set of control points on the plane, each at the center of
  54 a colored cell.  Every pixel within that cell is closer to that cell's
  55 control point than to any other control point.  That is what
  56 determines the cell's shapes.
