High-tech LEDs turning NYC skyline into a lightshow

The city’s skyline is becoming a rainbow of dancing colors as more tall towers add programmable LEDs to their tops and antennas. What was once stagnant and mostly white or a primary color is now alive with tint and effect heretofore only seen on the Broadway stage. Soon the nightly dance led by the Empire State Building will include the top of One World Trade Center, where the hues and swirling lights may be coordinated with those enlivening 4 Times Square and One Bryant Park — all owned in full or in part by the Durst Organization.
