Anamorphic Waterfall by Alessandro Diddi
In 1961, famous Dutch artist M.C. Escher printed a lithograph titled Waterfall. This print shows a seemingly impossible scene with water flowing uphill to create a perpetual waterfall using the same water over and over again. There is a paddle wheel at the bottom of the waterfall which we would assume is what powers the water back up the hill. Many artists have created derivative works or art inspired by this very intriguing concept.
Here, Italian artist Alessandro Diddi has sketched a three-dimensional anamorphic version of the waterfall that appears to literally stand off the page. In reality, it is all drawn on a perfectly flat sheet of paper. He has cut some sections of the paper away to help add to this optical illusion.
