Roughly 5000 objects, render time was about an hour and a half. I'd like
to use two or three times that many at least, but memory is a factor...

The prisms follow a (bumps scale 10) pattern; the blob components (yes,
the sand is a big-ass blob) does as well, but they're scaled a bit
differently to let the prisms poke out the top, and have a little random
displacement as well.

The water is just a huge transparent box with the typical "water"
modifiers, but I'm pleased with how it came out.

Sky radiosity was faked with a blue ambient. I like the effect of "real"
radiosity better, but it's so SLOW...

This is still a work in progress; it needs a better sky, some clouds,
haze in the distance, ruined objects half-buried in the sand, maybe some
plants and/or seagulls, etc etc etc.

Can't help, it reminds me of a BattleTech Field. Put some 'Mechs in it,
fighting with heavy weapons ...
The foreground looks very interesting. Never thought of Blobs to make a
terrain. I agree, the sky and the horizon needs work. I like it anyway.

The basalt columns look too perfect and regular...maybe if you randomly 
translated them some...or you could use vturbulence() or eval_pigment() 
to turbulate the prism points, just make sure they stay in the right 
plane.

Very good.  Suggestion: small gaps between each hexagon.  The water looks
really neat, except I wondered if it is over unaffected sand, or is there a
shift in the sand texture where the pools are?

I like the blob-scape. The prisms are too prefect-looking, perhaps a granite
normal would look more like basalt?

About the faked radiosity, a terrain like this would shine a warm, yellowish
light back onto the columns, I'm pretty sure.

Oh, and are the columns prefect hexagons? I still haven't figured out a good
way of rotating and translating perfect hexagons.

Also, shouldn't the sand be a gray/black? With those basalt columns 
poking through, it looks like it should have been formed by the rock 
weathering away.

There are two textures, one for wet sand and one for dry sand. The wet
sand comes up a little too far, though.. if you look carefully at some
of the higher sand you'll see it's a bit lighter.

As I imagined it, the sand got there by being blown/washed up against
the columns, so it doesn't necessarily need to match the prisms.. and
for that matter, the prisms were never meant to look like basalt
specifically, just hexagonal columns of some sort. At one point I
actually considered adding caps and making them quartz or amethyst.

They're not basalt, they're just.. columns. The image isn't meant to
look perfectly realistic and natural.

The vturbulence() suggestion is interesting, but I'd have to figure out
how it works first.
