The grey windows of the further streets are deliberate as the model was never intended to be seen from this angle. (All the action in the viral animation takes place within a single alleyway so the houses are only seen from the rear. Read chapter 7 for the details.) For the book cover these windows will have to be painted in individually. Also the wide screen format of modern monitors doesn't suit the portrait format of a book jacket so chunks of the landscape image will probably be chopped away. The distant houses, if SketchUp can ever be persuaded to render the middle distance, will probably have to be painted in later.
