Julia set, a fractal. Here created using the revesed formula in a itearted function system.

Formula used:

z_{n+1} = \sqrt{z_n - c}

One of the two roots are selected from some kind of function system and then after a number of pre-iterations (10-20) the position of Z is constantly plotted after each iteration. The method is wery much like the "random game" IFS method.

More fractals from my tools:

All fractals are from self-written tools - linear IFS images from my: "2D IFS Studio", non-linear (rev Julia) from "3D RJIFS", (that also writes 2D rev Julias), escape time Z² fractals from "Julia dream", the rest are from small "hacks".
