 In "Walls, Corners, Tubes" (2012), the artists present a series of objects with geometrical bodies which have the form of walls, corners, and tubes and are made alternately of black rubber and unfired clay placed on high, white pedestals.Both the shapes of the objects and their titles such as "Wand aus Ton" ("Wall of Clay", 2012) or "Röhre aus Gummi" ("Tube of Rubber", 2012) recall functional elements, such as those often found at building supplies stores.This was a pair of installations – one on the Valdresflye plateau in Norway and the other at the Serpentine Gallery in London in 2013.
