We heart Walker Art Center, not just for its relevant programming (Rirkrit Tirivanija and Dan Graham on exhibition, artist residencies), Herzog & de Meuron addition, and location in what might be the coolest, most underrated city in the Midwest. Someone over there has a got a sense of humor, too: senior registrar David Bartley stars in this video clip identifying the museum’s top five art objects that have to be identified as art, including a Yoko Ono text piece, an installation comprising 300 objects made from foam, and a 1991 Meyer Vaisman piece that looks and acts like a cardboard box.
