Except the set here is the fourth order mandelbrot and the output is given by the orbital density at each pixel weighted by |Z_n – Z_n-1| and I played with the colors a little.

Edit: I replaced the original rendering with a much larger one. 1401×1401 for those of you looking for backgrounds. It was supposed to be 1400×1400. Some loop is limited incorrectly.

Edit 2: Replaced the replacement with a new rendering. This one has 400 samples per pixel. That’s awesome.

Edit 3: I added a 3001×3001 render.

Like the title says.
