a building that talks to you

The permanent pavilion in the heart of Seoul ezhibit another possibility of the feature!

"The dome-like structure is made from transparent luminescent panels etched with a street map of the city. When air pollution levels improve in one area, that neighborhood’s corresponding panel is illuminated with LEDs. The casual passerby, therefore, begins to understand their city on an entirely new level - a largely invisible level. The same system that controls the illumination of the panels is also connected to a SMS hotline, so the “users” of this piece of architecture can essentially text message the building to get information about air quality. A building that talks to you."
