Zhang Zhang is an artist trained at the University of Michigan who created City Hour, a representation of a city in a room. According to the artist, he apparently intended to create an actual city, or at least a realistic interpretation of one in the room. That may have turned into a difficult task, or perhaps Zhang Zhang was more inspired by the abstract.
Either way, City Hour is the result. City Hour features a clock, tubing, and lots of caution tape. Check out the gallery for images of City Hour.
