Though the holiday season is over, we are happy to see the light displays continue setting NYC aglow on these short winter days. In downtown New York, visitors can bask in “Winter Glow,” a collection of interactive art installations lighting up Flatiron Plaza . Two exhibitions, “The Diamonds” and “Spectrum,” use movement and light to dazzle spectators. “The Diamonds” by Perséides Studio consist of three colorful structures that light up when they spin, featuring music by Stefie Shock that changes as the speed of rotation varies. Across the plaza is “Spectrum,” by Mirari from QDSinternational, which plays off of communication as it lights up to show sound waves pass through its circles. These interactive exhibitions are perfect for a little light therapy to brighten winter’s gloomy evenings.
