More than 300 works by contemporary artist and activist Ai Weiwei are being installed at spots around the five boroughs this fall for the “Good Fences Make Good Neighbors” show presented by Public Art Fund. Conceived in response to the global migration crisis, the show draws attention to the tense social and political battles surrounding the issue of dividing people, both in the United States and around the world. Spot the works at locations as diverse as the Unisphere in Flushing Meadows–Corona Park, Doris C. Freedman Plaza at the southeast corner of Central Park and the arch in Washington Square Park.
