Geometrical design is one of the most distinctive aspects of Islamic art and architecture. Islamic art is an art not so much of form as of decorative themes that occur both in architecture and in the applied arts, independently of material, scale and technique. The layers of surface decoration are increased and the complexity of visual effects enriched by the use of carpets and cushions, which often reflect the same decorative schemes as those found on walls and ceilings. Floors and ceilings contribute to the fluidity of space by the nature of their decoration, since they are often patterned in the same manner as the walls; sometimes, in the case of floors, the decoration actually reproduces carpets. There are some of islamic style interior design including Islamic Art Bedroom.
