Soon/ Now/ Gone engages with the Rail Park site’s history as a space for movement through a series of interactive installations and performances. Our point of departure is the Victorian era, where technologies such as the railroad and photography/cinema began to be used as a way to capture, collapse, and re-deploy time. In various tunnels and underpasses beneath the Viaduct section of the Rail Park, audiences will be invited to activate zoopraxiscopes—a pre-cinema device developed by Eadweard Muybridge in 1879—which will project hand-drawn images from rotating glass disks in rapid succession to create the illusion of motion. Each zoopraxiscope is fitted with a music device that visitors can use to activate an original soundtrack composed for the installation. By turning on and off different strains of the music and triggering sound effects, they will be able to create their own scores to the moving images on the tunnel wall.
