Hello everyone! Here's an idea I've been thinking of for quite a while. 
I'm pretty sure somebody has done something like this before... it might 
have been a grass texture, though.

What you see is actually a flat plane layered with over eighty 
semitransparent textures. Each additional texture is scaled slightly 
larger than the last, and uses a slightly altered color_map (actually a 
pigment_map, but it doesn't really need to be one anymore). The texture 
is then translated to the camera's X & Z coordinates to achieve a more 
proper illusion.

I can't really see a practical application for this trick. Even though 
this image rendered in a little over five minutes, it can get very slow 
when antialiasing is applied :(  Also, POV-Ray tends to throw an error 
if the number of texture layers goes over 100.

I still have yet to try it with radiosity. There's no reason why it 
shouldn't work.

The code has been placed (a little too hastily) to 
povray.binaries.scene-images.

Questions and comments are always welcome-
