No I havn't seen it but I think I get your drift.

Me too!  :)

Yeah!

While not exactly what is needed, the MegaPOV "cells" pigment
may be of help.  I don't use megaPOV myself so I could be wrong.

I think it might be better to write a macro to build actual
greebles (as objects) rather than just use a texture.  I've
written a few .pov files that attempt this but none are
satisfying.  Greebles / hull plates are hard to do!

One hint for you if you decide to try it yourself: if
you make a "tile" of greebles that is a mesh object, you can
tile it to the horizon.  Real cool.  Gilles Trans uses
this technique in his grass macro.  Really neat!
