Draw some random points on a map; colour code the map by which of the points is closest. Then you get a diagram like the above, called a Voronoi tiling. The animation shows what happens to the tiling as one of the points is moved. The top right shows part of a dragonfly wing, which appears to have a very similar pattern. Note that if you draw a line between two neighbouring points, then the boundary of their regions is at right-angles to this line. Can you see why?  [related film] [more] [my code]

I post original stuff about maths, space, computational linguistics and other things that I like. This blog is meant to be accessible and interesting to people of all backgrounds. My undergrad was maths in Cambridge, and I'm now starting research in Speech and Language technology. Email me at If you're new, check out this overview of my posts.
