OP (Optical) ART Op Art is derived from the constructivist practices of the Bauhaus. This German school, founded by Walter Gropius, stressed the relationship of form and function within a framework of analysis and rationality. Students were taught to focus on the overall design, or entire composition, in order to present unified works. When the Bauhaus was forced to close in 1933, many of its instructors fled to the United States where the movement took root in Chicago, where Anni and Josef Albers would come to teach.

ENVIRONMENTAL ART Earthworks Robert Smithson, Spiral Jetty, 1970. EARTHWORKS Land Art, Earthworks or Earth Art is an art movement which emerged in America in the late 1960 s and early 1970 s, in which landscape and the work of art are inextricably linked. Sculptures are not placed in the landscape, rather the landscape is the very means of their creation. The works frequently exist in the open, located well away from civilization, left to change and erosion under natural conditions.
