In this section, we'll go one step further and create additional Voronoi diagrams inside the cells of an existing Voronoi diagram. If we do this a couple of times, we get a nice nested Voronoi diagram:

What you can see here is that each Voronoi cell itself is divided into more Voronoi cells, and these smaller cells themselves are divided once again. The result is a very nice-looking nested diagram.
