“Circulatory Systems,” a mesmerizing short film by Worldgrapher and the Hong Kong-based production company Visual Suspect, deftly compares major highways to human arteries and veins. Made by simply cropping and duplicating real footage, the dizzying video twists and turns through complex interchanges that are repeated in patterns and emblazoned with headlights and the city’s glow. Many of the shots descend into the center of the transportation systems, glimpsing the moving cars and traffic lights.
