On January 12th, 2018 I added the ability to generate finer detail on the rooftop and grid-like facades on the building walls. The added edges on top of the building created a more believable look, and I was able to adapt the code to create randomized grid patterns on the walls.

The code still isn’t perfect; top building on the left has a definite overhang. Part of the work was figuring out where the rules failed in generating believable content and correcting as I go along.
