Feel-o-Meter Feels for a Whole City

In cities across Germany, Big Brother looks like a smiley face. The Fühlometer, a piece by Julius von Bismarck, Benjamin Maus, and Richard Wilhelmer, uses security cameras and sophisticated software to 'read' the faces of pedestrians, and then categorize them according to their emotions. The giant robot mirrors the mood of the city's inhabitants, and perhaps encourages them to put on a happy face... or else.
