Tom: Hehe thanks man

smoothing angle for the materialball mesh or ? if so nope the mesh is untouched, i just load it in and slap on the material and hit render.
Mihai: Oww, those are tough one's to create. I already tried bubblewrap plastic but it just looked like glass with bubbles. Foam i have no clue how to make nice, it's such a difficult material to do in more ways than one. Tirethreads and plasterwalls are relatively easy.
Brett: I'm glad you like it, although i can't take full credit for it since it's originally created by a Vray user and shared on the Vray materialsite. However recreation like this takes a bit of work and time to get it to look correct (i've done this before as you probably know). How the dragonskin can appear that 3 dimensional is because of the way the displacementmap is created, to be completly honest it's simpler than you may think. Just take a look at the map below.
The darker areas as you know are lower and the brighter one's are higher up and then with some clever fiddling then you can get it to look like each tile of the skin slides in under the other.
jomaga: Thank you!

and good work yourself because that one sure is a looker
