Maybe not magic, but after playing with Visual Lens on an iPhone we're absolutely floored (which seems to be the common reaction):

If you haven’t seen it already, Word Lens is a new iPhone app that instantly translates Spanish text into English and vice versa, via the medium of augmented reality.

...

When I first wrote about Word Lens after it had been released on Friday by Quest Visual, the above YouTube clip had attracted just over 7,000 hits. Three days later more than 2.1 million people have seen it.

The app is getting plenty of attention from the press, and for good reason. It’s fantastically cool, and it’s a good illustration of the way augmented reality is starting to move away from marketing gimmick to useful tool.

Head over to Forbes to watch the video now, and if you have an iPhone, you probably want to download the app.
