Madison Square Park Conservancy’s Mad. Sq. Art programme has announced a new installation to inaugurate the spring 2013 season: Topsy-Turvy: A Camera Obscura Installation by New York-based artists Sandra Gibson and Luis Recoder. “On view daily from March 1 – April 5, 2013, 10am-5pm, Topsy-Turvy will reimagine one of the world’s oldest moving image devices into a life-sized 10-foot by 10-foot structure,” the organisers say. “Park visitors will be able to enter the interactive, large-scale installation, which will utilize the physical properties of light to capture images of the surrounding Flatiron District in real time. This centuries-old artistic medium will alter how visitors experience the park and engage with the various elements of New York City’s urban landscape through a new and exciting lens.”
