Last night, I stumbled upon this rectangle of light on the Cornell Arts Quad and wondered if it was an art installation or just the random result of an open window with a projector running in Goldwin Smith Hall.

Update (Nov. 26, 2024): The Cornell Council for the Arts confirmed today that “what you captured was an unplanned, serendipitous art happening as far as CCA is aware. But we think it’s very cool!”
