Twenty-four searchlights, all high-powered, were set on rooftops around Philadelphia’s Benjamin Franklin Parkway last September and October. They were programmed, however, to avoid shining their spotlights on any physical objects: no buildings, no naked windows, no trees. Instead, they glimmered straight up into the sky: twenty-four columns of light responding — here solid, there faint, twitching and beating and sweeping across the sky together, then separating — to the voices of Philadelphia residents.
