By Advertising 2021 isn’t off to the most zen of starts, but a new work of art coming to the Garment District is hoping to bring a bit of soothing sparkle to midtown. Prismatica, an immersive art installation consisting of 25 rainbow-like prisms, will be installed this Monday on the Broadway pedestrian plaza between 39th and 40th streets, courtesy of the Garment District Alliance. The six-foot-tall prisms will reflect a kaleidoscope of colors as they move, creating a colorful environment for pedestrians to traverse. Along with the colorful reflections, musical sounds will create a truly immersive landscape along the public thoroughfare.
