I knew that a mobius strip such as that shown in Mobius Strip II (Red Ants) could be rendered as a real, 3D model. But I wouldn’t have expected that Escher’s Waterfall could actually be modeled and created for real. The Escher for Real website displays 3D models of several M.C. Escher drawings. It’s enough to make me want to play a game of M.C. Escherized Tetris! I wonder what that would be like?
