That is really cool.  Could you also post the source for the
first version please?

thank you

Certainly:

#macro C()function{pigment{crackle#end#local A=C()solid}}#local
B=C()}}isosurface{function{max(2+y*9-A(x*9,0,z*9).x*4,.2-B(x*9,0
,z*9).x)/80}pigment{rgb z+y}finish{reflection{.8 metallic.1}
ambient 0}}sky_sphere{pigment{agate scale 2}}

Enjoy :)

OH.  Clever.  I guess that if I traced it out the whole code, I should 
have seen that.

Thanks

is there a way of capturing the expanded source ?

similar to gcc -S||-s ??

I don't believe so, I think pov's # instructions aren't exactly a strict
pre-processor, though I might be completely wrong!

Though it's pretty easy to expand by hand, this is the more readable version I'm
going to submit with my entry:

#local A=function{pigment{crackle solid}}
#local B=function{pigment{crackle}}

#local Scale = 1/9;    //scale the isosurface to fit inside the unit sphere (the
default container object).
#local MaxGradient = 99;

isosurface{
    function{
        max(
            2+y/Scale-A(x/Scale,0,z/Scale).x*4,    //solid crackle pigment + y
=> horizontal roofs of buildings
            .2-B(x/Scale,0,z/Scale).x    //crackle pigment => walls of
buildings. .2 is the gap between buildings.
        )/MaxGradient   //adjust range of values to fit default max_gradient ==
1
    }
    finish{reflection{0,1}}
}

fog{
    rgb <1,1.2,1.33>
    distance .7
    fog_type 2
    fog_alt.1
}

sky_sphere{pigment{agate}}

sphere{<5.4,-3.6,5.4>, 5}

Nope. Macro expansions are done as the scene is parsed, not as a 
preprocessing step.
