LOL!
Yes it is very slow. Agreed.

In the code the, ScalingFactor is just an attempt to produce more little 
ones than big ones, and at the same time make the little ones inverse 
proportionately deeper.

Defining the pigment beforehand is just an attempt to get around the 
limit of 256 terms to be averaged.

Also I think it looks better, or at least closer to your example, with 
poly_wave set between 1 and 4.

The crater profile is mostly about the pigment_map of course

Otherwise just a bunch of averaged cylindricals rotated and scaled randomly.

Yes Slow. My example rendered -aa in about 5 minutes.

That you would use the idea or something similar to augment your texture 
was what I was thinking.  With a little less random, but rather more 
judicious application, you might get faster times and better effects.
