Escher’s Waterfall Machine Exists, Guy Develops Theory Regarding How it “Works”

Yesterday, there was a video floating around (seen after the break) of a wooden and “working” recreation of M. C. Escher’s Waterfall. The demonstrator poured water into one side, then the water seemed to flow around the machine forever. We couldn’t quite figure it out, as it didn’t seem to be computer-generated, but defaulted on the broad net of “camera tricks.” Luckily for us, and anyone else stumped by the video, David Goldman developed a theory and made a handy chart to illustrate the idea. The short of it seems to pretty much be camera tricks and editing magic. Make sure to head past the break to check out the original video.
