Chaotic Arboreum

Tree forms generated by a chaotic fractal.
The basic algorithm to generate the trees is just three lines of code, with 4 constants. Modulation of these constants within a narrow range results in various shapes of trees and leaf growth - which look like tropical, desert and temperate trees.
The several dry or green trees and the random scrub arise naturally from the fractal itself

Sky, clouds, moon and stars are added randomly, with some color combinations producing an other-worldly effect
