Word Lens from @questvisual
"Word Lens is an augmented reality application for the iPhone from Quest Visual that uses the built-in camera to identify text such as a sign in one language and have the words shown translated into another language. The words are displayed in the original context, on the original background. Word Lens was released on December 16, 2010, and received significant amount of attention soon after, including The Economist, CNN, and nearly 1.4 million views on You Tube in the first 3 days."
