May 15, 2018 · Sugihara has built a physical version of the Penrose stairs, an impossible object made famous by Dutch artist M.C. Escher.
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.
An impossible object is a kind of optical illusion. Impossible objects are also known as undecidable figures. In this kind of illusion, a person looks at a two-dimensional picture. The vision center of the brain does much of its work subconsciously and automatically.
The Penrose Triangle is an impossible figure (or impossible object or undecidable figure): it depicts an object which could not possibly exist. It is impossible for the Impossible Triangle to exist because in order for it to exist rules of Euclidean geometry would have to be violated.
The impossible cube or irrational cube is an impossible object invented by M.C. Escher for his print Belvedere. It is a two-dimensional figure that superficially resembles a perspective drawing of a three-dimensional cube, with its features drawn inconsistently from the way they would appear in an actual cube.
