This is pretty spectacular, as was the prior ovus example.

I think what Maurice is trying to point out is the "frosted" look of the blurred
pattern.
I think the earlier prototype StepNoise example was more impressive than the
current iteration.
And I'm not sure why you chose to do several experiments with start and end both
equal to 0.5 - as that is just the cells pattern.

But I must say that I really like this frosted look for an outdoor, weathered
piece of natural stone, as this is really what it looks like, with dust, and
evaporated rain, and pollen, etc.  Adding that displacement or normal really
gives it that natural look as well.

I think Maurice is looking for that lack of micro-surface texture that leads to
a lot of air - which has a different ior than the minerals and leads to that dry
paper / freshly applied transparent tape look.  Polishing, wetting, and waxing
gives it that sharp, crisp, high-contrast look with more saturated colors and
clearer delineations between the grains.

At least that's what I'm speculating.

However, all in all, this is very pleasing, and extremely encouraging progress!
