The Phantom City project has created an iPhone app that lets you see a New York that’s never actually existed. Instead of what’s really there, in the city, the Phantom City app shows you images of previously planned (or dreamed) buildings and parks. It’s like a history of New York, except that it’s a history of thoughts, as opposed to actual occurrences.
More and more iPhone apps (and apps for those other smartphones that never get any attention) are focusing on interacting with the real world while using your virtual device. The Phantom City app is a creative way to do just that.
