“Temporary projects change people’s expectations for what they are allowed to do there and what’s possible,” Roberts says. “Representation is really powerful, and it’s something that Mabel and I talked a lot about with Marching On: The way that young black people are represented, the way that people in public space are represented—it evokes possibilities of liberation expression that might feel otherwise forbidden or discouraged. Even with when the [Columbus] City Hall installation comes down, you have all the people who will say: ‘We used to play there, I wonder if we should do that again?’”
