Sugihara’s Circle/Square Optical Illusion
thingiverse
This 3D file showcases Sugihara's Circle/Square Optical Illusion. Kokichi Sugihara created the video "Ambiguous Optical Illusion: Rectangles and Circles" on YouTube, where he demonstrates a 3-dimensional shape that appears as a circular cylinder but looks like a square cylinder in a mirror. Mathematics Professor Dave Richeson at Dickinson College designed the 3D file, which can be printed and cut to replicate the illusion. He has shared a pdf file for this purpose and wrote an article about the illusion in Math Horizons magazine's September 2016 issue. To print the shape, use a LulzBot TAZ 6 printer with rafts and supports enabled, and set the infill to 10%. The Geogebra file that describes the design can be found on geogebra.org. The 3D file is available for download at Dickinson College Professor Dave Richeson's website.
