Editing Impossible cube (section)

==Usage in art==
In Escher's ''Belvedere'' a boy seated at the foot of a building holds an impossible cube. A drawing of the related [[Necker cube]] (with its crossings circled) lies at his feet, while the building itself shares some of the same impossible features as the cube.<ref>{{citation
