The Media Architecture Biennale in 2018 will explore the role that Media Architecture plays as infrastructure well suited to placemaking and smart city initiatives, large and small. How can the various scales and systems that media architecture operates in be connected to support social structures within the territory of a city? A country? Or even a planet? How can we think critically and creatively about the past, present, and future developments of expressive, connected, and reactive architectural elements at both a local and global scale?
