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.
