I settled on just a plain white mainly because I wanted to see the effect of the
water and photons.  There wasn't an actual scene so much as there was a test (or
series of tests) to try and find a decent way of getting water to be the right
color across different depths.

I made it on the heels of another scene, where I wanted the water to be that
nice green color close at the shore (presumably in part because of the yellow
sand underneath), and have a darker blue green with some variations due to
depth and underwater objects.

I still haven't gotten it quite right, but I have found that it is sometimes
better to turn extinction 0 in the scattering block and control things via
absorption.

Realistic beach scenes are tricky (or so I assume, as I've never actually
managed a realistic one myself).
