Hipstamatic is a little $1.99 app that we’ve had a lot of fun playing with over the holidays. It treats your iPhone pictures as you shoot them, applying filters and edge effects. Nothing we couldn’t do ourselves in Photoshop, but to have it happen semi-instantly is pretty rad and makes me feel way better about the iPhone’s dinky camera. The user interface is brilliantly analog retro, and there are alternate lens/film/flash pals at a small cost.
