Everyone has seen those perplexing drawings by M.C. Escher and marveled at their paradoxical nature. Confusing images that could never be real. Until now.
Gershon Elber of the Computer Science Department of Technion, Israel Institute of Technology has done just that. He has designed 3D shapes that, when 3D printed and viewed from specific angles precisely reproduce the Escher effect.
The work is not limited to "simple" objects, such as the Penrose Triangle, but also includes some of Escher's large scenes, including the Waterfall, Belvedere and Relativity. The STL 3D model file is provided by Elber for some of the items, including the Penrose Triangle and Escher's Relativity.
