Tree Streetmap

Have you ever thought about a mental map of where you live?
It's all pretty geometrical, streets go off at right angles, roads are straight

Then you look at a streetmap programme like Google Maps , and all of a sudden it seems a bit chaotic, and you wonder why people would ever build something so irregular.

I happened to take this picture today looking up the trunk of a small tree, and then realised how much the small branches look just like a streemap.

There's some kind of uncanny connection here, but it's too deep for me to work out, so I'll leave the fractal mathmatics and chaos theories to the genii of the World.
