" All in all it's just another brick in the wall".- Pink Floyd.
Not only the 3D effect, but just about the only way to get a truly random color pattern in the brick. I've done the same thing with shingles, and if you think that's nuts,,,, try painting that random pattern of color on commercial brick material!
That !, is some really beautiful masonry, I have got to try that!

P.S. Those wouldn't be chads from a card punch would they???
