I went back and looked at the brick texture I used for the buildings and did
some more work.  The attached image is a closeup of a brick wall as an
isosurface using a brick pigment pattern, applying some noise for the brick face
texture, and added some variability in the depth of the brick so they aren't all
flush with the face of the wall.

Still not completely happy with the look and texture of the mortar, but I think
these bricks are a big improvement on the original without individually creating
each brick.
