I found this great little app for the iPhone, called Hipstamatic. It's a combination of old film, lenses, and flashes from old manual cameras. It can create some very interesting effects with your photos. I've been playing around with it for a bit, and I really like it. You can pair up different lenses and different films, or you can just shake the iPhone and the application will randomize everything, giving you a very different and unique effect. Like this.
