I just couldn’t resist playing a game with these shadows on the floor of this hallway. It’s something I’ve often done ever since I discovered the perfect geometric patterns they make on the ground on sunny days. Each day, I would try to tread on the smallest number of shadows possible, avoiding as many as I could – but it was really difficult. My feet always ended up partly covered by a streak of darkness. Light and shadows, that’s what the trajectory of mankind is made up of.
