Hacker George Hotz, also known as Geohot, has created an innovative new photography app, Reactions. It's designed to use both the front and rear cameras of an iPhone at the same time, capturing both a photograph, and the photographer taking it, and displaying them both in the same image. The idea and the reason for the name is that your reaction to your subject will also be captured.
It's also designed with social networking in mind, with each photo being auto-published to Facebook, unless you quickly tap a cancel button.
The app itself is awaiting approval from Apple, and will be available on the iTunes store after that. The face of the brand, Geohot himself, is most famous for his hacks of the iPhone and PS3 which got him into legal hot water some time back.
