Generates realistic looking trees from a chaotic fractal
Based on my dweet here - https://www.dwitter.net/d/24167


Unlike IFS fractals which are designed to draw a certain shape, this particular fractal happens to generate these forms serendipitiously - which is quite a wonder.

The fractal itself needs only a few lines of code to generate.


Random colored skies and clouds are drawn, as well as moon an stars for the night-mode variations.
The image is rendered incrementally and takes about 10 seconds to generate.
