An art installation created by Canadian artist Caitlind r.c. Brown made from over 1,000 working light bulbs on pull chains and some 5,000 burnt-out bulbs. Visitors can interact with light installation by pulling the chains turning some lights on or off, creating a flickering aesthetic of an electrical cloud. The cloud structure was part of the nuit blanche all-night contemporary arts festival in Calgary, canada. Check out the video below. via: Dvice
