Fly By Night

What happens when you attach LED lights to 2,000 pigeons and release them at dusk to fill the sky? You get Fly By Night, the public art project from Duke Riley. The effect itself is pretty mesmerizing to see, albeit somewhat hard to capture on video. This Creators Project profile is a nice bit of insight into the project and Riley's respect for the animals and undertaking.

Understandably, there is some controversy around the project, as the pigeons aren't exactly volunteering for the job but, personally, I feel like the evidence leans towards the birds not being traumatized.
