Abstract

This article presents a class of 3D optical illusions, in which the apparent orientation of an object changes to the opposite in a mirror. We first show the mathematics behind such illusions, and then present a method for designing objects with desired appearances. Next, we show two simple subclasses, which can be realized using paper, and hence can be useful even for children to create their own illusion objects.
