Impulse is an interactive art installation made of twelve oversized seesaws that transform the Broadway pedestrian plazas into an urban playground. When visitors to the seesaws climb on top and move them, the seesaws glow with light and emit randomized musical sounds. Located on Broadway in the Garment District between 37th and 38th Streets, Impulse was created by Lateral Office and CS Design in collaboration with EGP Group, and first presented as part of the winter Luminothérapie light festival in Montreal. When we visited the installation over lunchtime this week, we heard a lot of happy shouts, laughter, and the sound of general merriment on the seesaws. Creos, the tour producer of the installation, says the seesaws embody “ideas of serialism, repetition, and variation to produce zones of intensity and calm” and they “animate the public space and its occupants during the cold and dreary winter.” That much is certainly true. The seesaws are on display through January 31.
