I think, with the aqueducts, and all the yukkuri guro in this, that this pic is probably a fanart/shout-out to the site http://thewaterducts.sakura.ne.jp/, where many of the yukkuri stories originate.

I believe the original is by Escher.

Take it escher!!!

I lol'd so hard at the Alice yukkuri raping the Marisa yukurri in the bottom left corner.

I'm guessing if you don't know Yukkuri fandom, that's pretty funny. Rather normal stuff for an Alice type to be doing, though.

It's like an endless river of Yukkuri pain.
