Every year, the Madison Square Park Conservancy funds a public art installation. For 2010, the project is so ambitious that it will not only spread outside the park but even above it.
British sculptor Antony Gormley has created 31 naked statues of himself and placed them in the park, on nearby sidewalks and up on the rooftops and ledges of nearby landmark buildings, including the Flatiron and Empire State. The project is called "Event Horizon" and is actually a restaging of a similar piece he did in London back in 2007. The difference here is that he's got some taller buildings to work with and a concern from local police that the statues might be mistaken for suicidal jumpers.
