About this model
This is a 3D file based on Sugihara’s Circle/Square Optical Illusion. Kokichi Sugihara created the video "Ambiguous Optical Illusion: Rectangles and Circles." In it he shows a 3-dimensional shape that looks like a circular cylinder but in a mirror looks like a square cylinder. The 3D file was created by Mathematics Professor, Dave Richeson, at Dickinson College. He has blogged about the project and has shared a pdf file that can be printed and cut to replicate the illusion. He also wrote an article about the illusion in the September 2016 issue of the journal Math Horizons. Geogebra file and description
