the conception of very complicated spaces, while the ability to link computer models to manufacturing jigs (CAM - Computer-aided manufacturing) allows the mass production of subtly different modular elements to be achieved at affordable costs. Also, Gehry is noted for producing many physical models as well as computer models as part of his design process. Though the computer has made the designing of complex shapes much easier, not everything that looks odd is "deconstructivist." Gallery Critical responses Since the publication of Kenneth Frampton's Modern Architecture: A Critical History (first edition 1980) there has been a keen consciousness of the role of criticism within architectural theory. Whilst referencing Derrida as a philosophical influence, deconstructivism can also be seen as having as much a basis in critical theory as the other major offshoot of postmodernism, critical regionalism. The two aspects of critical theory, urgency and analysis, are found in deconstructivism. There is a tendency to re-examine and critique other works or precedents in deconstructivism, and also a tendency to set aesthetic issues in the foreground. An example of this is the Wexner Center. Critical Theory, however, had at its core a critique of capitalism and its excess, and from that respect many of the works of the Deconstructivists would fail in that regard if only they are made for an elite and are, as objects, highly expensive, despite whatever critique they may claim to impart on the conventions of design. The difference between criticality in deconstructivism and criticality in critical regionalism, is that critical regionalism reduces the overall level of complexity involved and maintains a clearer analysis while attempting to reconcile modernist architecture with local differences. In effect, this leads to a modernist "vernacular." Critical regionalism displays a lack of self-criticism and a utopianism of place. Deconstructivism, meanwhile, maintains a level of self-criticism and a dystopianism of place, as well as external criticism and tends towards maintaining a level of complexity. Some architects identified with the movement, notably Frank Gehry, have actively rejected the classification of their work as deconstructivist. Critics of deconstructivism see it as a purely formal exercise with little social significance. Kenneth Frampton finds it "elitist and detached". Nikos Salingaros calls deconstructivism a "viral expression" that invades design thinking in order to build destroyed forms; while curiously similar to both Derrida's and Philip Johnson's descriptions, this is meant as a harsh condemnation of the entire movement.
