This art installation created with over 1,000 working lights and some 5,000 burnt-out bulbs definitely evokes a smile when you see it lighting up the night sky. What's more it's interactive where the crowd can turn some lights on or off by pulling chains causing the luminous cloud to change in intensity — from light to dark like a thundercloud.
The artist responsible for this incredibly complex, interactive art piece called "Cloud" is Caitlind r.c. Brown, who created the piece for the recent Nuit Blanche Calgary in Alberta, Canada.
As the video below shows, the whimsy of the experience is evident on the faces of those who got to play with it. You can actually hear the groans and shouts when the cloud grows dark triggered by some random chain.
The beauty and fun of it all is that the participants never knew which chain causes the cloud to react in what way, so they kept pulling away with glee. With reactions like that, it certainly could never be called just some boring art exhibit.
