I had the idea of an amazing "box" with an infinite folding in x,y directions (normal fold acts only once, so each iteration generates nine spheres) and no fold at all in z direction - like the amazing surf, more or less.
Result looks very interesting, because each sphere is covered with an infinity of spheres, I thought that share this new idea can be useful to Mandelbulb users.
