Interesting app released today for the iPhone. Word Lens is a free app that translates signs on-the-fly, and applies that translation to the image presented on the iPhone's screen. Have a look at the video below—it's amazing stuff. And yet another example of the death of traditional signage.
The free version currently just flips words around, but there's also a Spanish-to-English and English-to-Spanish dictionary. I wonder how well it will deal with more script-based or pictographic style languages, such as Urdu or Mandarin?
