Amazing app - translates text on the fly with phone camera

It's been a long time I've been totally amazed on some SW. I do follow lot that what's happening on application development aroung the world, but this totally blew me off, Check this out. It translates language on the fly with phone camera. It's the first time I've really thought that these augmented reality apps make lot of sense. It would be so cool to try this out.

App is from Word Lens from QuestVisual. Check the video out:




It's just so cool. And what shocks the most, it is really usefull.
