Some cracked earth that I whipped up for my entry. :-)

I could probably do this as a height field, but the way that the 
isosurface came out is so cool...

declare cracks = function {pigment {
         crackle
         turbulence 0.1
         color_map {[0 rgb 0][0.1 rgb 1][1 rgb 0.5]}
         scale 0.5
}}

isosurface {
         function {2 * y - cracks(x, y, z).red}
	// etc.
}

You know you've been raytracing too long when you wonder if the human 
eye uses ray-tracing, and at what it's frames per second rate is?
