Word Lens uses your device's camera to translate Spanish into English (or vice versa) on the fly. And it doesn't just serve up plain text, it superimposes the translation back onto an image of the original surface, even matching its size and font. Point your camera at a sign reading cerrado and the app shows a picture of the sign reading closed. It's as close to magic as we've seen.
WIRED Translations from the future.
