Ah, that's my luck.

I have seen some macros that allow some form of surface deformation, and
then the deformations from pigment patterns I have seen folks use seem
nice, but my goal would be something altogether more powerful and more
fully fleshed out, while occurring internally instead of by macro. 

Any reasonable progress in that direction I would be happy to add my
patronage to. I am a huge fan of true displacement. :)

This is a good sign then, and perhaps due to it already being on the list
and having a source backing somewhat in place would serve to move this up
the list.

Im going to check out the other posts I missed due to nit being subbed to
this group previously, then collect what I have from those and see if we
can get some kind of rather short (less than 5 items) that are reasonable,
sizable, and that we can take and move forward on with coming up with some
first stab at with building some kind of system to go forward with.
