Though, some of the dots are off-center on the path; and he did say "hand-made and painted", so maybe he made a big block and started painting it.
Ah, but if he just made a big block and then started painting, he'd of known about the Bricklimit before he started painting.
Nope. Engine restrictions.
-snip-There's your blur.
Anyone can change that with a little Java scripting. ;D
