For some reason, the thing that came to mind upon seeing the picture right after 'scale modeling', was 'Ray Harryhausen'...

C.T. 

That one is definitely awesome. But if you know what to look for, you can figure out where the seam is because of parallax. Right at the seam, the figures on opposite sides are quite a lot different in size, because the "small" ones are a lot further away from the camera.

Given that legos are standard size, and the figurines are too, that wasn't really something the guy could do anything about. Wicks (this photographer), on the other hand, can make his models to whatever scale he needs them to be, so his equivalent of Escher's waterfall (the first picture above) doesn't have that kind of scaling issue. He's deliberate made the piece in the front slightly smaller than the one in back so that there's no obvious parallax change at the seam.
