A while ago there was a craze of Menger sponges, Serpinski pyramids, and 
other fractal shapes...I think there were at least a dozen different 
methods being tried for Menger sponges alone. Some of them reached quite 
high recursion levels...

	You're right, I thought about this too late. OTOH, since the value of
the noise3d won't change much over the size of one sphere, you might
find that the other equation gives adequate results and renders faster
(again completely untried...)
