Penrose Square Mugs

Penrose Square, is an impossible shape based on the Penrose Triangle. It's an optical illusion consisting of an object which can be depicted in a perspective drawing, but cannot exist as a solid object. It was first created by the Swedish artist Oscar Reutersvärd in 1934. Independently from Reutersvärd, the triangle was devised and popularized in the 1950s by psychiatrist Lionel Penrose and his son, prominent Nobel Prize-winning mathematician Sir Roger Penrose, who described it as "impossibility in its purest form. It is featured prominently in the works of artist M. C. Escher, whose earlier depictions of impossible objects partly inspired it.

Design based on impossible objects, such as those popularized by Escher, Reutersvärd and Penrose.

A different colored version of the Reutersvärd’s triangle, a great optical illusion. A two-dimensional optical illusion perceived as a projection of a three-dimensional object that cannot exist
