Made by Bernard Helmstetter with the following procedure:
First draw a 4000x3000 image of the Mandelbrot set, with two different colors (green and blue for example) for the outside: Image:Mandelbrot set from moire patterns first step.png. The colors have been chosen based on the values of an expression of the form ((int) floor(f(r))) & 1, where r is the potential, and f is a function varying rapidly, so that moiré patterns appear.
Then, edit under gimp to extract interesting features. The first important steps were: gaussian blur (radius = 2px), decompose to HSV and keep only V, invert colors, dilate, erode twice.
