The Lego illusion works only if the photograph is taken from exactly the correct viewing angle. But in a picture taken from another angle ( bottom left), you can see that the edges of the staircase do not meet. Belvedere In Belvedere, for example, many impossible features are found. Some of his most famous are Belvedere and Waterfall. Escher provides the most popular examples of impossible figures in his drawings and woodcuts. In their photograph of the finished sculpture, it looks as if the staircase is continuous. The interrelationships between the two opposite guidelines provides the illusion of an impossible picture. Lipson and Shiu spent considerable time studying Escher's work before beginning construction. Some of the people are ascending the staircase, while others are descending. The original work by Escher, a 1960 lithograph, shows a large building with an endless staircase on its roof ( bottom right). Escher works in Lego blocks, including this model of Escher's Ascending and Descending ( top). ( bottom right)Īndrew Lipson, a self-described “professional nerd” with no official connection to the Lego Group, and his friend Daniel Shiu have rendered five M. ESCHER'S ASCENDING AND DESCENDING, © 2016 THE M. Unlike classic monuments-such as the Lincoln Memorial in Washington, D.C.-which can be perceived by either sight or touch, impossible sculptures can be interpreted (or misinterpreted, as the case may be) only by the visual mind.ĬONSTRUCTION BY ANDREW LIPSON AND DANIEL SHIU PICTURES COURTESY OF A. That is, they are interested in shaping real-world 3-D objects that nonetheless appear to be impossible. Several contemporary sculptors have taken up the challenge of creating impossible art. As long as the local relation between surfaces and objects follows the rules of nature, our brain doesn't seem to mind that the global percept is impossible. They also reveal that our brain constructs the feeling of a global percept-an overall picture of a particular item-by sewing together multiple local percepts. These effects challenge our hard-earned perception that the world around us follows certain, inviolable rules. Maurits Cornelis Escher was not a mathematician. Mathematical physicist Roger Penrose drew his famously impossible triangle, and visual scientist Dejan Todorović of the University of Belgrade in Serbia created a golden arch that won him third prize in the 2005 Best Illusion of the Year Contest. Trying to give to mathematical formulas a concrete image, MC Escher produces pictures of impossible objects. Escher, for instance, depicted reversible staircases and perpetually flowing streams. In an impossible figure, seemingly real objects-or parts of objects-form geometric relations that physically cannot happen.
