Here I used the new function erm, function in povray
3.5 to take an input image map and process it, generating
greyscale, sepia tone, negative, weirded out, etc. versions
of it.
	Source in povray.text.scene-files.

And, for those who haven't seen it because they don't read p.t.s-f,
there's a more complex example of the same thing under the subject 
"halftones" in the same group.
