Named after the Swiss crystallographer Louis Albert Necker, the Necker cube was first named and described in 1832 but its history actually reaches back to the ruins of Pompeii, found as a floor mural, dated 79 C.E. The illusion is appreciated as you shift your point of focus over the composition of a grouping of rhombi. Found famously in M.C. Escher’s Metamorphosis I, the Necker cube remains relevant across a multitude of design fields and continues to spark the imagination and wonder of the infinitely curious. Last tidbit for all you 1980’s gamers, let us not forget Q*bert, hopping endlessly from cube to cube in arcade rooms around the world.
