Ah. Textures aren't quite so readily apparent in photos, but they are definitely part of the whole effect. I remember seeing a sculpture at a local art show many years ago and all it was was a large, whitish rock. But the rock had been polished smooth in some areas and roughened in others. I was quite taken with it (I do love rocks!). It did seem quite odd, tho, that the artist didn't want anyone to touch it.
