What if buildings could talk? David Benjamin and Soo-in Yang (aka "The Living") answer the question, helping lead the burgeoning movement of interactive architecture, which seeks to engage citizens with environmental and other issues. Living Light is a permanent outdoor pavilion in the heart of Seoul, Korea with a dynamic skin that lights up to show real-time air quality data in the city's neighborhoods. It also gathers data from people texting the pavillion to chart public interest. Citizens can enter the pavilion or view it from nearby streets and buildings, and they can text message the building and it will text them back.
