Fine, but smoothen them out in random parts, to make it look more realistic.

borders still look a bit awkward for coastlines maybe passing them through some smoothing procedure could make them more easy on the eye

Neurons firing. I recognise one of those blobs as being oddly similar to the real-world administrative area where I grew up, not that I learned the actual shape of it until a few years ago. The blobs around it don’t match though.

For a moment I thought that it’s a map of Germany.

this is amazing and I had been looking for a good voronoi implementation for ages! ty so much.

This looks a lot like the crystal orientation map of a metal sample

Slartibartfast would be impressed.
