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.

Cool optical illusion geometric design. Great gift for nerds. Cool triangle shape. Minimalist geometric optical illusion is cool for geeks.

The Penrose stairs or Penrose steps, also dubbed the impossible staircase, is an impossible object created by Oscar Reutersvärd in 1937 and later independently discovered and made popular by Lionel Penrose and his son Roger Penrose.

Maurits Cornelis Escher, the wizard of illustration and graphic illusionism, his drawings are always intriguing and fascinating.
