Visitors at Calgary's first Nuit Blanche festival were
treated to gorgeous illuminated cloud made from burnt out incandescent bulbs in
the city's Olympic Plaza. Designed by Caitlind r.c. Brown and collaborator
Wayne Garrett, CLOUD is a large-scale interactive sculpture. Over 6,000
reclaimed bulbs cover a wire skeleton frame, which is illuminated with
energy-efficient CFL bulbs on the inside. Festival-goers merrily gathered
underneath the cloud, playfully turning lights off and on with metal pull
strings into the wee hours of the night.
