I think this could be a great entry. I'm guessing you did it something like
this:

#include "functions.inc"

plane
{
 z, 1

 pigment
 {
  mandel 1000
  interior 1, 1
  translate <-0.4021, 0.2, 0>
  scale 100
 }

 finish
 {
  ambient 1
 }
}

Whoops, I didn't need the functions.inc!
Here is one at 96 chars:

plane{z,1 pigment{mandel 1000 interior 1,1 translate<-0.4021,0.2,0>scale
100}finish{ambient 1}}

Here's another fun way to use mandel:

#declare f=function{pigment{mandel 1000 interior 1,1 translate -0.17
color_map{[0 rgb 0][1 rgb 1]}scale 2}}light_source{0.2*y rgb
1}height_field{function 999,999{f(x,y,z).gray*0.1}pigment{rgb
1}translate -0.5}camera{rotate 45*x translate -0.7*z}

246 bytes :-)

You don't honestly want to sell this as a shortest version, do you?  I 
mean there are dozens of chars to save here.

I think dere oughta be a rule -- "bring it" :-)
I want to learn how to shave more chars... let's see the shorter version!

my hints:
- you don't need the zeros before the dot '-0.7' == '-.7'
- you don't need a space between a number and a keyword or variable
  '1000 interior' == '1000interior'
- you can thus also replace '45*x translate' by 'x*45translate'
- you do not need a space before a '-'
   'translate -0.7' == 'translate-.7'
- 1000 or 999 do not make much difference (except one char)

that gives:

#declare f=function{pigment{mandel 999interior 1,1translate-.17
color_map{[0rgb 0][1rgb 1]}scale 2}}light_source{y*.2rgb
1}height_field{function 999,999{f(x,y,z).gray*.1}pigment{rgb
1}translate-.5}camera{rotate x*45translate-.7*z}

which saves 14 bytes in total, not realy the dozens Christoph talks
about, so there is probably more.

Sweet! I wish I knew about the numbers thing before I put my entry in. I
think I might also be able to lose [0rgb 0] as well to get:

#declare f=function{pigment{mandel 999interior
1,1translate-.17color_map{[1rgb 1]}scale
2}}light_source{y*.2rgb1}height_field{function
999,999{f(x,y,z).gray*.1}pigment{rgb1}translate-.5}camera{rotate
x*45translate-.7*z}

I don't have pov at work, though; does the above compile?

There is - but hey, this is a *contest*... ;-)

After you replace 'rgb1' by 'rgb 1' it does.
It is not the same image though ;)
You can gain another char by using '.red' for '.gray'
(I do not know why. I never had time to investigate
much about function :( I mostly do meshes and patches.)

... and source of my irritation. Now if a day could heve the same number of
hours as short code chars... I hope I will find some hours for participate.
