Inspired by local weather phenomena, Creative Machines installed an interactive, LED-illuminated sculpture entitled Chinook Arc by artists Joe O’Connell and Blessing Hancock. The sculpture is located in the City of Calgary and drew its form from the Chinook arch, a cloud formation that periodically blankets the city, the Canadian prairies, and Great Plains. The actual Chinook arch results in brilliant colors transforming the sky. Likewise, the Chinook Arc sculpture is a circular band of light that dynamically changes colors at night mirroring the monumental effects of clouds. The artwork contains an optical sensor which allows visitors to control the sculpture’s lighting by waving their hands or playing a video on their cellphone.
