Perhaps Gehry could be called a deconstructionist architect who explores ideas of chaos, breaking boundaries and multiple viewpoints. However, Gehry prefers to not categorize his work with any style or movement. Perhaps his approach to architecture is pointing the way to something totally new. Gehry's work is often more related to abstract sculpture than to architecture. You can't help it.
Sculpture is a three-dimensional object and so is a building.
Modern art or modernism is characterized by changing attitudes about art, an interest in contemporary events as subjects, personal artistic expression, and freedom from realism. Modernism can be seen as artists' attempts to come to terms with urban, industrial, and secular society that emerged during the 19th century in Western society. A term used to describe a diversity of styles and mediums explored by artists beginning in the 1970s. Initially applied to architecture that reacted to pure geometric modern styles, Post-modernism is often ornamental and borrows from past art and architectural sytles, putting these elements in new combinations and contexts. In art and literature, a tendency in recent work to subvert or pull apart and examine existing conventions having to do with meaning and individualism.
