The Seoul Bienniale of Architecture and Urbanism was an array of exhibitions throughout the Korean capital celebrating the growth and development of the city beyond regulations and standards into the realm of the commons. This companion illustrates and describes exhibits relating to such matters as Seoul-on-Air: augmented environments for urban activism, Smell = Information: what could happen when invisible information--from smell molecules--is the starting point for acting and reacting, An Atlas of Machine Landscapes: a tour through the post-human architectures of machine vision, and The Ideology of Sharing Culture: open-source architecture as a design factor and research tool.
