Since I posted my ocean rock face, I might as well share the sand I did before it. This is another substance drawn more from memories than recent research or reference. Some things just flit about the edge of my consciousness waiting for an opportunity to pop out, I guess. Because this is "tidal" sand, I added a water layer, with displacement in the height and normal. I included controls to alter the color blending and HSL; so I'm posting a lighter, less saturated version of the sand for contrast.
