I've tried a few times to draw Escher, but it's so difficult to do his works justice in ASCII art. Here's another mathematical figure; not impossible, but confusing. The rings cannot be separated, yet if you remove one the remaining two are not linked. __,---.__ __,---.__ ,-' _,---._ `-< _,---._ `-. ,' ,-' ,^-. `. `-. `. / ,' / ,' `. \ `. \ / / / / \ \ \ \ ; ; ; ;_,---._: : : : | | ,| |_,---._ `-. | | : : ,' : : 7-. `. ; ; \ \ / ,' \ \ / / `. \ / / \ `. / / \ `. ,' / \ \ ,' / `.

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. -Arthur ObASCII: _ `.\ ._, ,-+._J | ( __> `._, `-\ ; _.,) ._] '_.- `-./``-/ |-' < [ \,' Apparently, Escher can draw lizards better than I can, too.
