Could you please share a code of this 'moss and grass' ?

I rendered without any change, using the commented line :
sphere{0,1,-0.8 scale <1,0.01,1> Point_At_Trans(Normal) translate
Normal*Distance*1.2}
Will try with the other options.

Added #switch(frame_number), a few #case(n)...#break and rendered with +kff7
First one : Rounded faceted sphere
Second : Sharp faceted sphere
Third : Pockmarked sphere
Fourth and following : It get fuzzy.

Attached is something like what I used - it produces the bottom part of
the attached image... The coloring comes from Ingo's light colors.
I don't have the original scene anymore as I was playing with this and
that. Plus, I was using my yuqk fork for which the "numerical issues"
are a little different the official releases of POV-Ray. This shown in
the top row of the attached image where on the left is Ingo's original
at 1e-3 and the same rendered with the yuqk fork on the right(*)
The biggest changes for the fuzzier results was not using the larger
positive sphere and changing the negative squashed spheres into positive
components.
Bill P.
(*) - Part of what is happening in the original posted scene is that as
we scale down in y, except for the edges, the negative components start
to cleave off little round bits of the larger sphere rather than blunt
it in a faceted way. The yuqk fork shows this a little better, because
it's numerical accuracy with blobs is a little better.

Thanks for sharing scene and detailed comments, right 'out of the box'
it looks completely different (attached), but I will try to tune it up.
Now I'm thinking about adding it and similar abstract scenes
to https://povlab.online in separate section - 'artifacts' :)

The one on the left could be further modified to produce some nice crater
impacts.
