I feel your pain. I spent the entire day messing around with an
isosurface brick with vertical ridges and some noise to make it
clay-like.

I've realised a few things whilst working through things:

1) everything you know is wrong.
2) experimentation is as good as knowing math ;)

My method is a bit sloppy, and the rendering is slow, but it's a great
brick. I even made an unevenly-troweled wall out of them. they look so
real.

keep on plugging, don't give up ;)
