Renowned art display confuses straphangers

A new art exhibition is leaving some Brooklyn commuters confused.   
What appears to be an encasement of metal around the bus shelter on Fulton and Smith streets is actually a piece of art that's part of a citywide installation by renowned Chinese artist Ai Weiwei.
The exhibition, Good Fences Make Good Neighbors, is a social commentary on current geopolitics, raising awareness on the way fences divide people.
However, most people thought it was just there to protect the bus shelter or to offer a place to sit.
