Red, Yellow and Blue by Orly Genger

Madison Square Park’s latest art installation is a series of colorful wavy walls made up of painted, hand-knotted nautical rope—1.4 million feet of it, which comes to 20 times the length of Manhattan (the rope weighs 100,000 pounds). The primary-colored walls will dissect the park into spaces both hidden and visible, making it the ideal spot for a game of hide-and-seek, or just a great adventure with a camera in hand.
