MRB Cube
thingiverse
The Mysterious Recreational Brain teaser The Mysterious Recreational Box (MRB) is a complex 3-dimensional puzzle. It is an amalgamation of multiple mathematical ideas from Kurt Gödel's incompleteness theorems, M.C. Escher's artwork, and Douglas Hofstadter's 'Gödel, Escher, Bach.' The puzzle was originally described in Hofstadter's Pulitzer Prize-winning book of 1979 by mathematician David Chudnovsky. It is called an MRB cube because it resembles a simple cube. However, this simple cube hides numerous mathematical patterns that reflect several properties from Gödel's work and Escher's creations. In 'Gödel, Escher, Bach,' Hofstadter presents many analogies between art and mathematics using both visual and literary examples of recursion, infinity, paradoxes, and self-reference. These are some of the same properties displayed within an MRB cube.
