Emphasis should be on topography, climate, light, tectonic form rather than scenography and the tactile sense rather than the visual. Frampton draws from phenomenology to supplement his arguments. Postmodern architecture is an international style whose first examples are generally cited as being from the 1950s, and which continues to influence present-day architecture. Postmodernity in architecture is generally thought to be heralded by the return of "wit, ornament and reference" to architecture in response to the formalism of the International Style of modernism. As with many cultural movements, some of postmodernism's most pronounced and visible ideas can be seen in architecture. The functional and formalized shapes and spaces of the modernist movement are replaced by unapologetically diverse aesthetics: styles collide, form is adopted for its own sake, and new ways of viewing familiar styles and space abound. Classic examples of modern architecture are the Lever House and the Seagram Building in commercial space, and the architecture of Frank Lloyd Wright or the Bauhaus movement in private or communal spaces. Transitional examples of postmodern architecture are the Portland Building in Portland and the Sony Building (New York City) (originally AT&T Building) in New York City, which borrows elements and references from the past and reintroduces color and symbolism to architecture. A prime example of inspiration for postmodern architecture lies along the Las Vegas Strip, which was studied by Robert Venturi in his 1972 book "Learning from Las Vegas" celebrating the strip's ordinary and common architecture. Venturi opined that "Less is a bore", inverting Mies Van Der Rohe's dictum that "Less is more". Following the postmodern movement, a renaissance of pre-modernist urban and architectural ideals established itself, with New Urbanism and New Classical architecture being prominent movements. Deconstructivism in architecture 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, (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. Important events in the history of the Deconstructivist movement include the 1982 Parc de la Villette architectural design competition (especially the entry from the French philosopher Jacques Derrida and the American architect Peter Eisenman 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 in Columbus, designed by Peter Eisenman.
