Sugihara Cylinders

Rows of colorful 3D printed cylinders that look like different shapes, such as hearts, diamonds and crescents, when seen in a mirror

In Fall 2021, GMU Math 401, Mathematics Through 3D Printing, created mathematical optical illusions. These are objects whose shapes look totally different in the mirror. In each case, you are looking at an object and its mirror image. A diamond becomes a crescent moon, a Batman symbol is right side up both in reality and in the mirror. How does it work? Mathematics! And a clever idea by Sugihara.
