This JSL was inspired by some gray scale images by Misha Friedman. His images are better.

There's no real 3D here, the perspective is odd, it is just a toy for a rainy Saturday. The attached JSL is set up to generate images into a directory. I picked a few of the better ones and cropped them a bit. The JSL is not optimized; each picture takes a minute or so to render.
