Art Exhibition at City Hall Park in NYC is Free But Not Much to See

Image Object exhibition at City Hall Park is a collection of contemporary sculptures/installations (2015) that are provided by the Public Art Fund.  I found the large bust of a woman, by Ross-Ho, encapsulated by a square neon green frame, interesting.  I thought the 2 white marble "Moore" like pieces by Jon Rafman graceful and beautiful (although obviously appropriated from Moore's works.)  And, the shiny purple sculpture of an arm with a finger holding up a basket is taken from pop-culture; an appropriated photo of a Harlem Globetrotter was fun & forgettable.  These were 3 of the 7 large installations clustered at the southern tip of the Park.  All recent works have a common thread; merging technology (technically mediated imagery) into objects.  Still, art is in the eye of the beholder as the old saying goes and this self-annointed art critic says don't go out of your way to view the pieces.   However, free is free.  And, if you're on jury duty (technically not free) use your lunch break and make it your get-away destination.
