Our experiences of objects depend heavily on our understanding and expectations of the materials from which they’re made. This often occurs without conscious thought. The Exploratorium draws attention to this invisible interaction by creating works from unusual or unexpected materials, like for example, a Hummer made of Styrofoam. The exhibition features works by artists Andrew Junge, Ulrike Palmbach, and Flash in Tonyland among others. The cavernous Palace of Fine Arts itself becomes part of the canvas as animated artworks hang from the building’s exposed beams and trusses.
