Calgary, AB (2010) – The Bow River, which runs through Calgary, Alberta, got a little PR help in the summer of 2010 in the form of a seven-day living art installation and colorful balloons to illuminate the river at night. The installation was part of six-part public art series aimed at reminding Calgarians about the Bow River’s “purity, abundance, and indispensable role in connecting all life-forms to the river.” The illuminated spheres of light by Laurent Louyer and the lighting studio Creatmosphere represent the Bow River’s four water sources: rainwater, groundwater, glacier, and snowmelt. SOURCES & RIVER OF LIGHT were part of the “Celebration of the Bow River” festival, attracting thousands of people to gather at the riverbanks.
The light sculptures are meant to map the physical and social demands on the Bow River and focus viewers’ attention on the intricacies and interdependencies of the river’s life cycle and water sources. The installation ran a 7.5-km stretch of the river from Edworthy Park to Prince’s Island Park. The installation, which ran from August 14 – 21, 2010, concluded with the spheres of light being released into the river and floated down the 7.5-km stretch to Prince’s Island, where they were diverted into Prince’s Island, where they were diverted into the lagoon and collected by viewers.
