ITERATIVE FUNCTION SYSTEMS or IFS

I discoveed the fascinating
Iterative Function Systems world by years 1990.
From a simple set of
2 linear equations of 2 unknown variables, one can
(provided that one find the right coefficients !),
recreate plants such as fougeres, trees and all kinds of vegetals one can continuously transform.

Of course, the right coefficients are very accurrate, and difficult to find. It demonstrates that the world is not created to random !
Let download this program :

Here is an exemple you can download here
