Hipstamatic is one of my favourite camera apps for the iPhone. It's a super, high-quality app for getting a cool retro look in your photographs. But, what I find makes it even more fun is that is has a cool feature where by you shake your iPhone to get a random lens/film combination. And, if you want to take the fun up one more notch take a self-portrait. Because the application does not allow you to flip to the front facing camera you are essentially shooting blind. The one-two combination can make for some great shots, like this one.
