This is one of those “augmented reality” apps that have been getting attention lately. The idea is to overlay information onto a 3D view of your surroundings. The new iPhone 3Gs makes this possible, and acrossair has taken advantage of it to produce something really useful – locating nearby subways. Watch the video below to see how it works.
Currently they are waiting for approval from Apple to get it into the AppStore. I’d love to see it in there before Saturday morning, since I’m heading to NYC this weekend and I can’t wait to try it out.
