Kaleidoscope based on Metamorphosis III, by M. C. Escher. Woodcut print, 1967-1968. Maurits Cornelis Escher,
a 20th century Dutch artist famous for his etchings and illustrations, uses
painstaking perspective and geometry to create his art - challenging the
viewer to second guess what is physically possible.
M.C. Escher designs his transformation print 'Metamorphosis III' for post
office in The Hague, unveiled Feb 20, 1969.
It is wide enough to cover all the walls in a room, and then loop back onto
itself.
