Perpetual Waterfall
Create an illusion inspired by M.C. Escher's "Waterfall" (1961). The image should depict water moving upwards from the starting point "x", making a left, right, and then left turn at 90 degrees between three medium-height castle towers. The water then reaches a waterfall, where it pours back to the starting point "x", creating a perpetual motion effect. The scene should include detailed and realistic elements to emphasize the optical illusion, with the water seamlessly flowing through the described path in an endless loop.
