Aram Bartholl, "Keepalive" at Springhornhof Neuenkirchen, comissioned by Center of Digital Cultures Leuphana University Unless you notice the little plaque marking it as art, you might easily miss Aram Bartholl 's newest work, which debuts on Sunday and blends seamlessly into its surroundings in the wilderness of Germany. " Keepalive " takes the form of a modified 1.5-ton boulder that lies in a forest clearing next to a small creek, on the grounds of the Springhornhof , a museum of site-specific outdoor sculpture.
