Yeah; I didn't mean to suggest otherwise.  Yours is a really great
picture!  But the receding perspective on the stream is harder to grasp
in ASCII art, so I thought that making the stream obviously "recede"
behind the building was a good way to make the optical illusion stand
out, even if it did make it less faithful to the original.

Apparently, Escher can draw lizards better than I can, too.
