Check out these Cinemagraphs by Jamie Beck and Kevin Burg. More than a photo, but not quite a video. Pretty sick.
they are .gif files much like many that people use, but the difference is that the movement is specific to only a very small feature thus making it look like it is a single image that is magically moving in a single spot. I'm going to try this out to see just how hard it is, but I don't think it should be too difficult.I can't even begin to fathom how that is done!? someone please enlighten me!
