BTW, you can make it shorter by using pattern functions instead, 
eliminating the need for the .x's:
#macro C()function{pattern{crackle#end#local A=C()solid}}#local
B=C()}}isosurface{function{max(2+y*9-A(x*9,0,z*9)*4,.2-B(x*9,0
,z*9))/99}finish{reflection{0,1}}}fog{rgb 1+y/5+z/3distance.7
fog_type 2fog_alt.1}sky_sphere{pigment{agate}}sphere{9*(.6-y),5}

It also renders faster...

Nice...I think I saw curly bracket used as birds somewhere else, though 
they were large and close up so you could see what they were.

Oh, I came up with a way to get sloped roofs on the 
buildings...basically, make a pigment function with a solid crackle 
pigment_map of multiple random gradients. Scale the crackle pattern 
really big along the y axis so it's essentially 2D and won't interfere 
with the sides of your buildings, and just add the result to your 
isosurface function. Still working on getting it completely right...
