This interactive Cloud created by by artist Caitlind r.c. Brown. The Cloud is made from 1,000 working lightbulbs on pullchains and an additional 5,000 made from donated burnt out lights donated by the public. It was appeared on September 15th as part of Nuit Blanche Calgary in Alberta, Canada. Visitors to the installation could pull the chains on and off creating the flickering aesthetic of an electrical cloud.
