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” (2015) 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. Unlike an actual rock, however, “Keepalive” houses a fire-powered wifi router that, once activated, connects users through their phones to a list of downloadable survival guides — transforming the boulder into a hard drive of stone. Permanently installed, the piece has a sturdy structure meant to stand the test of time. It contemplates the amount of value we place on data and the types of survival tools we may require in a tech-driven world.
