@kolenk FRACTAL:a curve or geometric figure, each part of which has the same statistical character as the whole. Fractals are useful in modeling structures (such as eroded coastlines or snowflakes) in which similar patterns recur at progressively smaller scales, and in describing partly random or chaotic phenomena such as crystal growth, fluid turbulence, and galaxy formation.

Basically trees that have patterns that reoccur forever as you "zoom in" or lower the scale of the view of tree. Its... like a tree with branches that have more branches that have more branches that have more branches... and so on. https://medium.com/@abhinav.mahapatra10/python-beginner-diy-make-fractal-trees-b1a0903414a9
