Wow. That may be your best one yet. I...I can't even think of a name for it. Your art is amazing Cris.

Do you use Bryce for the water & sky?

No way, Deb, nothing here is hand-made, also Bryce it far more complex and give a lot of options. The scenery is incredibly simple: the values are fractal-generated and passed on to the PovRay sky_sphere identifier. PovRay is the render engine I use. The water is a set of definitions on the plane Y, just like the sky, only lower than the position of the camera.
Down here is a simple scenery to notice how is everything generated -mostly- on two basic planes... The scenery is extremely simple; I didn't want to lose time on that, the computer generates the scenery values and period, enough to me. :-)

The link above is wrong.

That's the one.
