Here's my latest image. Comments are welcome.

For the texture on the ground I took a picture of a piece of road. I then used
that picture as a bumpmap.
The problem I now have is that I want to apply a normal{ waves ... texture to
the ground aswell. However, If I include that then it overrides the bumpmap. Or
the bumpmap overrides the waves normal. Depending on the order in which they
are placed. Any suggestions about how to combine them are welcome.

// untested code

#local f_Road = function { pigment { image_map { sys "road_image" } } }
#local f_Wave = function { pigment { waves } }

#local Norm = normal {
	function {
		f_Road(x,y,z).gray + f_Wave(x,y,z).gray
	}
}

Hmm. WHat I did was to define a plane{ ... } with a
texture{normal{bump_map{...}}} and a separate pigment{waves}. The attached
picture is the result. Now to find out how to make it accept a pigment{color
...} aswell...
