Yes Mike's page is a treasure trove of hints and examples.
Thomas used Mike's Cityscape in our image "Dhalgren".
I have not used the isosurface approximation macro but I notice that 
there are two files adapted by Jaap Frank. I have a couple of macros 
written by Jaap and they work very well.

Oh! Joy. :)

But you might want to render it many times as you adjust things like 
your texture or camera view. Just a thought.
Looking at your image in p.b.i. it is quite regular. I would try the 
approximation macro.
