"Silent Lights" installation is Rainbow Road IRL.

Several artists have pooled their talents to light up the path beneath a busy expressway in Brooklyn.

Silent Lights is an architectural series of gates that frames a pedestrian pathway by day showing constant movement through shadows.  It transforms sound into patterns of light at night as it mimics movement with led lights, reflecting and interpreting movement and sound.  There are no blind spots, the path is always lit and each gate responds to create a dynamic installation.  Cars drive by, microphones pick up the sound from traffic, a computer processes the sound and triggers each gate to light up sequentially.  As noise increases, the light from each gate intensifies.

If you get mugged while walking down this path, you’ve only got yourself to blame. Drop a few bucks at their Kickstarter page.
