Troika sent us documentation of Shoal, their newest public artwork for the Corus building in Queens Quay East on Toronto's Waterfront. 467 independent, iridescent objects that resemble fishing lures "liquify" the ceiling of a 50m long corridor, mimicking the interdependency patterns seen in schooling fish. According to Troika, this is meant to change "the spatial experience of the corridor while opening up the surrounding architecture infinitely towards Lake Ontario."See the video up top for a demonstration of Shoal's rich material dimensions, from mesmerizing iridescence to the seamless motion made possible with custom built electronics, stepper motors and control circuits. Like all of Troika's work, the installation is accomplished without being overwrought—the electronics are there to amplify the captivating qualities of the light-reflecting objects without overpowering them.
