Hipstamatic is an application for your iphone that comes equipped with some nifty lenses, flashes and film (which add different borders). If you aren't a burgeoning photographer, this application is a lot of fun...because really, it can make almost any photo look neat. It's only a couple of bucks, which as far as additions to a camera go, is sorta like how when a movie ticket cost a nickel, old school fun.
I love the app a lot and of course inflict it upon my dogs like every five seconds; they're hoping the hype dies down soon, because I'm so annoying. So you are going to be seeing a lot more of these shots. Until I find myself irksome.
