M.C.Escher's "Circle Limit III" by Vladimir Bulatov via Flickr
An Escher-inspired poster, titled Spot the Opportunity. This "poster was done by use of a tessellation technique. Tessellation is a process of creating a two-dimensional plane using the repetition of a geometric shape with no overlaps and no gaps... [T]essellations frequently appeared in the art of M. C. Escher, who was inspired by studying the Moorish use of symmetry in the Alhambra tiles during a visit in 1922."
