Fake Blue Manure Is Latest Berlin Art Installation

BERLIN, GERMANY - AUGUST 07: Visitors walk past one of four piles of fake blue horse manure outside the Neue Nationalgalerie art museum on August 7, 2012 in Berlin, Germany. The four piles are an art installation by artist Martin Gostner titled "The Oriel of the Blue Horses" that refers to the Expressionist painting "The Tower of the Blue Horses," which has been missing since it was confiscated by the Nazis in 1937. Gostner's work is a clandestine installation. (Photo by Sean Gallup/Getty Images)
