Isometric City Block #1

The sketch continues my isometric grid experimentation. It creates a city block by randomly placing eight building designs on the block. There are eight grayscale palettes which are randomly used to color the buildings. The building designs were based on a page found in the book "Learn To Draw: 3D Isometric Stuff" (ISBN: 979-8545970063). I tried to reproduce the buildings as faithfully as I could and then worked out the logic to randomize their placement. Each building uses its own JavaScript file.
