Right on the southeastern corner of the park are changing exhibits. Currently Ai Wei Wei has exhibits all over NYC called Good Fences Make Good Neighbors.
This is the first one I've come across but then I haven't been walking around the city. It's called “Gilded Cage” and like the exhibit I saw this past summer, it's meant to evoke the luxury of Fifth Avenue – both past and present – and the those who live on the outside of that luxury.
You can go inside the cage. There are turnstiles inside also.
