Always keep handy your gremlin-gun when approaching an old scene file. They
breed like rabbits. I've started fumigating my old scenes to cut down on
ammo expenditure.

Is the sand an isosurface? For ripples, I think I'd try adding a stretched
leopard pigment function into the mix, and maybe some very low level
turbulence (high octaves and omega) to get a slightly gritty feel. As I
mentioned in my cgsphere thread, this is proving reasonably successful for
my sand.

Good luck with the curtains - cloth is something I've not yet turned my hand
to, for very good reasons!
