Photo taken with iphone + hipstamatic app. Hipstamatic takes square format photos using digitally simulated analog film. Sounds weird, but you can indeed make interesting photographs this way.
I have no connection with Hipstamatic. A friend of mine, a professional photographer, showed me some of the work that he had done with the app — that is how I got hooked.
zipTimer: an iPod/iPhone app for pacing piano practice, workouts, you name it.
