IMAGE DESCRIPTION: 

Dunes, rocks, the moon - well, my humble try at a desert landscape render.

DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 

This image is pure POV-Ray. 
The dunes are a heightfield made from a quilted pattern. This was the hardest
part. Although the final code to make the HF is very short and simple, it took
quite some experimenting before I discovered that this pattern makes good
dunes.
The rocks are isosurfaces based on the rounded_box function with a spline
function and some pigment functions added to form the rock shapes.
There is one lightsource only and no radiosity. As a result this scene renders
quite fast.
