Make 3D Printed Optical Illusions

The video tutorial explains how to create 3D printed objects that appear as impossible shapes, such as an arrow that always points right. Based on Professor Kokichi Sugihara's work, the tutorial covers the design process, including converting 2D shapes into 3D objects that create optical illusions. It details the steps to make these objects 3D printable using STL files and discusses automating the process with programming. The tutorial provides example code in Matlab and Python for creating custom shapes.
