It’s just a pile of 6,000 old incandescent light bulbs held together with chicken wire, I keep telling myself. But that’s simply not true. Cloud, by Caitlind Brown, is simply captivating.

Inspired by “cartoon-aesthetics, an interest in diffused light, peer-inspiration, and cloud-gazing,” Brown fashioned together this art installation from thousands of old, donated light bulbs, wrapped around 250 working compact fluorescent bulbs. It’s hundreds of pounds of extremely fragile glass, and visitors stand right below, eagerly pulling on its raindrop-like strings. With each tug, a small bit of light flashes, like lightning.
