Don't be startled if you spot some human bodies in the nooks and crannies of Wall Street this Sunday and Monday. Bodies in Urban Spaces, a free “performance” created by Vienna-based Dorner, will transform the city’s financial district with human architecture. We're told that Dorner will be "shepherding a group of brightly-clad performers through the concrete terrain surrounding Wall Street—its narrow cobblestone streets, historic monuments, park benches, global financial institutions, and mom-and-pop stores." Here's a look at what you might see this Sunday (at sunrise) and Monday (at sunset). If you spot these human sculptures around town send us your photos or tag them with "Gothamist" on Flickr!
