DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 

Jee... That's what I call a question. It's too much to write it all down...

I started with the stones; in a lot of scripts of course. All a tiny bit shifted
and all a 
tiny bit turned (random). When the stones were allright I started on the window
in the wall. 
It's incredably difficult to build a window like that with that much objects.
You can't
simply union all the backwall stones and then perform a difference: it would
take too long.
So I've avoided a lot of extra calculations by dividing the wall in parts.
That's good enough
to render the image in a reasonable time. Oh: by the way: the stones are all
superellipsoids;
no cubes are used in here.

So far for the stones-section. The water was next to come. Thank God I had the
Chris Colefax
excellent include file for the water coming from the cylinder (difference with
another cylinder
to make it hollow, of course) The next problem was the water underneath. The
ripples are all
centered around the point of the water coming in the pool with some crackle to
make it more
realistic. The smoke on top of it are in fact two layers of half-transparent
textured planes.
Halo's took too long to render... The drops from the ceiling are made with blobs
to make 
them pretty and then scaled along the y-axe to suggest that they are falling.

The fire is a plane with a very difficult texture on it.

Oh: by the way: all textures are handmade with a little help of a utility I made
to easily 
pick colors. (that's the reason of the weird values).

I won't explain the heart of the source-code: the textures. It would take too
long to explain.
But I haven't ever seen textures of this size.

I think that should do most of the scene. The rest can be found in the source
code.
