nice graphic for spacefiling Julia or Mandelbrot set.
This fractal set is generated by a repetitive fractional polynom for fractals.

I don't know what fractal program was used for render this graphic.
If I try to make same fractal on FRACTAL EXPLORER or ULTRAFRACTAL, the graphic occur a lot of filled circles with a self color by bailout.
Must other fractal program to remove those residual filled circles.
