Voronoi Diagrams

To create a set of random points ("seeds") in a canvas, then break up & color the canvas into regions where every point is the same color as the "seed" point closest to it. (It'd also be nice to get an example of the related Delaunay Triangulation, but I can't quite put that into words, so I'll just link the wikipedia pages for both [Voronoi Diagrams](https://en.wikipedia.org/wiki/Voronoi_diagram) and [Delaunay Triangulations](https://en.wikipedia.org/wiki/Delaunay_triangulation).)
