Here are images from Roxy Paine's public exhibition "Conjoined," from Madison Square Park in New York City (2007). I stumbled into the park quite by accident, trying to find places to explore while waiting for my younger brother to finish up his video game class so we could head home to NJ. Spent a lot of time in museums/parks in those two weeks. Imagine my surprise in finding these towering welded stainless steel trees.
Didn't discover the artist's name until seeing his exhibit on the roof of the MET in September of 2009 ("Roxy Paine on the Roof: Maelstrom"). More photos of that at a later date. In the meantime, check out info on the expired MET exhibit HERE. (Roxy is the dude with the sweet muttonchops).
