Designed by Rafael Lozano-Hemmer, this setup consists of “144 robotic fluorescent light fixtures controlled by 7 computerized surveillance systems”. The light tubes continually rotate to create “patterns of light that are ‘paths’ or ‘corridors'” as persons walk underneath. Video after the jump.
When two or more people are detected, the system rotates the fixtures so that “light corridors” are created between them. As many people walk in the court, the light reflect the influence of all of them creating complex patterns similar to isobars. Every few minutes, the system enters an “interlude mode” showing random orthogonal arrangements
