In this episode of Art and the Senses, we follow two stories. The first shows how Yoko Ono challenged the rules of art in her "Painting to Be Stepped On" (1960), a piece of canvas laid on the floor, asking viewers to touch it. The second takes us on a “touch tour,” a long-running Access program at MoMA in which educators lead visitors who are blind or have low vision through the galleries to experience works through touch, a sense that shapes perception, memory, and emotional connection.
