The document is a synopsis and reaction paper for a course on theories of architecture and urbanism. It discusses applying postmodernist ideas to architecture in Las Vegas. While modern architecture aimed to change existing environments, postmodernism in Las Vegas uses symbolic signage and references to the past. This creates superficial meanings but also acts as eye-catching attractions for passersby. The graphic signage along highways has become the defining architecture, effectively communicating complexity through symbols seen from a distance at high speeds.
