Human-size sticks of chalk—each 64 inches long and approximately 120 pounds—fill Gallery 7, which has been transformed into an environment open to spontaneous mark-making. With a chalkboard spanning the walls and floor, this art installation by collaborators Jennifer Allora and Guillermo Calzadilla has been presented in cities around the world, including Lima, Peru; Zapopan, Mexico; Sydney; Paris; Boston; and New York. Chalk provides a physical forum for participants to exchange ideas, evolving into a social and political portrait of the community.

Puerto Rico–based Allora & Calzadilla have collaborated since 1995, creating works that reach across sculpture, video, performance, and photography. Through their incisive practice, they engage with questions of history, culture, and geopolitics.
