This ambiguous cylinder object was developed for George Mason University's Math 401: Mathematics through 3D Printing class, taught by Dr. Evelyn Sander.
This object belongs to the Reflexively Fused Objects class of optical illusions discovered by Kokichi Sugihara (RFO). RFOs are identified by their appearance when seen at a 45-degree angle on a horizontal mirror. Because of the difference in viewing angles between the direct and mirrored views, this is conceivable. Because both viewpoints are 90 degrees apart, the form depicts both of them at the same time. It should be impossible to make a quadrilateral in this way, yet the picture of a quadrilateral is formed by adjusting the edges such that they appear different from different views.

This object was created in Mathematica. I generated two functions based on the image that I provided. one for the quadrilateral's front and one for the quadrilateral's back. It's worth
