Organic Abstraction is an artistic style characterized by "the use of rounded or wavy abstract forms based on what one finds in nature." It takes its cues from rhythmic forms found in nature, both small scale, as in the structures of small-growth leaves and stems, and grand, as in the shapes of the universe that are revealed by astronomy and physics. Nautillus shells and honeycombs are examples of organic structures that have served as inspiration for this work, along with the bones and musculature of the body, both human and animal. Although organic abstraction has been described as a "feature" rather than "an actual movement," the style arose in part as a reaction against the austerity of mid-century Constructivist art and is best known for its practitioners of the mid 20th century, whether in sculpture—Jean Arp, Constantin Brâncuși, Henry Moore; architecture—Eero Saarinen, Frank Lloyd Wright (for the Guggenheim Museum); or design—Charles Eames, Isamu Noguchi. Some recent critics contend that the term Biomorphic Abstraction is coming to be used more generally to describe contemporary art produced in this mode. Source: Wikipedia (en)
