This video has been making the rounds on the internet for about two years, but every time I watch, it brings a smile to my face.

In 2009, São Paulo based musician Jarbas Agnelli came across a photo in a newspaper of birds perched on electric wires. His musical curiosity took over, and he decided to find out if the birds created some sort of melody based on their positions on the wires. Sure enough, a surprisingly well constructed melody emerged, and Agnelli posted the final result in this video.

Agnelli later gave a talk at TEDx São Paulo to discuss the piece and has been interviewed with the original photographer, Paulo Pinto, in the same newspaper that the photo first appeared.
