The original of the wallpaper Hexagon is a photograph of the ground of Passeig de Gracia, a boulevard in Barcelona. Just like several buildings on the boulevard the paving stones are designed by the Catalan architect Antoni Gaudí (1852-1926). Gaudís architecture is considered to be art nouveau but his unique aesthetics has made an impression in many different architectural styles. He often mixed geometrical patterns with inspiration from religion and the sea. Organic forms such as seashells often recur in ceilings, stairs, and constructions. Or as in the case of the paving stones of Passeig de Gracia, joint together with geometrical hexagons. The pattern is lovely to walk on but could also be perfect as a ceiling wallpaper.
