michpc, who correctly guessed that this is a photo of the "Flurry" screensaver on a Mac. Others knew it was a Mac screensaver, but michpc was the first to provide the essential detail of which screensaver it was.

Dancer used a Canon EOS 5D with an exposure of 1/250 at f/4, ISO 1600, and a focal length of 55mm.
