"The traditional concept of space is a concept based on perspective. It was developed half a millennium ago and perceived space from a fixed and absolute viewpoint as being an endless, homogeneous and three-dimensional expansion. The decisive novelty brought about by cubism was the displacement of this absolute perspective by a relative one. Artists experience the space's unreal comprehensiveness as its essential element ... and that one has to move through space to be able to really experience it as being three-dimensional" [1].
