It was perfect.  Maybe too perfect. LOL.

Seriously, thanks.  In part it might be do to the EBlob functions in 
iso_csg.  They seem to give smoother transitions than blob primitives no 
matter how you set the threshold.  The texture is pretty much identical 
to the one I posted earlier.  I would like to also try something derived 
from granite or wrinkles.  Interestingly, combining the IC_Diplacement 
with IC_EBlob, you seem to only get results within a narrow band of 
thresholds or something. I sometimes mess with the pigment maps on the 
underlaying functions for instance, like maybe sometimes only a map like 
[0 rgb .98][1 rgb 1] will give results.  On this one I used [0 rgb .4][1 
rgb .6] for instance.  I really don't understand what is going on.

Yes, but that is another whole bog to get through and my first 
encounters with it (shoe models) did not meet the success with it that 
others seem to get.  As I was saying to Shay, the whole 
background/setting problem is significant because it really goes to 
meaning.  I don't think I'll find a good answer soon.  I was trying to 
place it on a table with maybe some foliage behind, but it's a 
meaningless slog for me.  I much more like the effect of photo product 
shots with a color screen behind where the object either hovers in space 
or makes the barest concessions to gravity and support.

Actually I was using something more like that. 2-points I think. This 
render was not originally intended to be shown so the bg is incomplete 
and the lighting purposely stark.  But when the render just went on and 
on...I don't know, I decided to post anyway.  I will learn more 
self-discipline as I learn to work with these long renders I am sure.
