There's a great story behind Cinemagram. A small team who built this noticed that, in the art and advertising world, designers were using "cinemagraphs" as advertising, the engagement of a nice picture coupled with a bit of motion picture. So, they built dead-simple consumer software on the iPhone to empower anyone to make this art, and the feeds are stunning. I'll share some more that I think are powerful, but check it out: http://itunes.apple.com/us/app/cinemagram/id487225881?mt=8

I love that image of an individual bird flying. It's visceral.
