One of the more interesting apps I’ve run into in a while is Echograph, which lets you shoot some video on your iPhone then grab a likely still photo from the video, then use your finger to paint motion back into the still photo. What’s this give you? An animated GIF image that’s either wicked cool or really stupid. What works best? Something with repeatable motion, usually an element of nature like the wind or water.
