Fractal Sphereflake

Select with the sliders in the upper left corner the generation of the fractal (G: 0-5, G = 6 or 7 are also possible but the animation of the fractal might be slow) and below the size ratio (RS: 2.0-4.0) between the spheres of the fractal generations, the total size of the fractal (R0: 50-250), the greyscale of the background and the speed of the 3D-rotation of the fractal.
