Some time ago (way back in 2002) I had a play with using the crackle pigment 
in an isosurface to create a city, the results of which can be seen here:

I decided to revisit that concept because I just noticed how interesting 
crackle metric 1 form <-1,0,1> looks, and this is what I came up with!

It makes a more interesting looking city IMO. The roads look a bit wierd at 
the moment (but still better than previous roads). Hopefully with a bit of 
work on texturing I can get something that's completely procedural but looks 
pretty realistic!

Comments & suggestions appreciated!
