Currently just a Kickstarter project, the idea is pretty great: take the classic idea of a simple decorative pin (a.k.a. "button" — like the old plastic and metal kind with some pop punk band name and logo you may have worn on your jean jacket back in high school when you were trying to look cool, but in hindsight, seems embarrassing and regrettable) and make the face into a thin LCD screen. Then, sync it wirelessly to an app on your smartphone that lets you change the image displayed on the screen to pretty much any photo or moving image that you want. The face can even display GIFs, use for the increasing numbers of us who communicate primarily or solely in that medium.
