That looks AWESOME. I can see a lot of utility with this macro for making
thinks like stamped text, worn stone tablets, knobby bronze objects, etc. I
have tried creating this effect in the past with a low resolution
heightfield, but without your square dividing algorithm, the results were
quite poor.

If you can wait for just one more day, I have been doing some speed
experiments and can speed up the normalizing algorithm a LOT. I have removed
the extra steps from the algorithm, "functionalized" all of my formulas, and
combined some processes. And in defense of all of my rewrites. I can at
least say that my first version worked as intended. <g>
