Explaining Escher

Maurits Cornelis Escher was an artist of impossible images. His drawings worked prefectly on the two dimensions of a sheet of paper but were impossible to exist in the real world. Some of the images show people, animals and objects that gradually turn into something completely different, while others create amazing optical illusions. 'Belvedere' is one of his most impressive works and this video is an attempt to explain what happens when you try to make the picture tridimensional.
