A gradient going from black through red through yellow to white. You
can make a height_field based on your grayscale image and give it a
gradient y pigment with a color_map like:

color_map { [0 Black][0.25 Red][0.75 Yellow][1 White] }

or similar. This, and any other weird stuff as well. That's what art
is for.
