what is deconstructivism ? ( Quick !!!!!!!!!!!!!!!

Deconstructivism in architecture, also called deconstruction, is a development of postmodern architecture that began in the late 1980s. It is characterized by ideas of fragmentation, non-linear processes of design, an interest in manipulating ideas of a structure's surface or skin, and apparent non-Euclidean geometry,[1] (i.e. non-rectilinear shapes) which serve to distort and dislocate some of the elements of architecture, such as structure and envelope. The finished visual appearance of buildings that exhibit the many deconstructivist "styles" is characterised by a stimulating unpredictability and a controlled chaos.
Some of the architects involved have been influenced by the writings of the French philosopher Jacques Derrida and his ideas on deconstruction, though the extent of this is still questioned; others have been influenced by the idea of reiterating the geometric imbalances of the Russian constructivist movement. There are additional references in deconstructivism to other 20th-century movements: the modernism/postmodernism interplay, expressionism, cubism, minimalism and contemporary art. The attempt in deconstructivism throughout is to move architecture away from what its practitioners see as the constricting 'rules' of modernism such as "form follows function", "purity of form", "truth to materials", and expression of structure.
Important events in the history of the deconstructivist movement include the 1982 Parc de la Villette architectural design competition (especially the entry from Jacques Derrida and Peter Eisenman[2] and Bernard Tschumi's winning entry), the Museum of Modern Art’s 1988 Deconstructivist Architecture exhibition in New York, organized by Philip Johnson and Mark Wigley, and the 1989 opening of the Wexner Center for the Arts, Columbus, Ohio, designed by Peter Eisenman.
