Xsights is an Israeli startup that develops interesting technology that allows for transformation of static objects like billboards, posters, printed images and more into interactive multimedia experiences using your cellphone camera. Theoretically, you could use Xsights to dynamically obtain more information based on e.g. words from a newspaper article, a landmark, a photo of an actor on a movie poster, a street sign, etc. This bares some resemblance to augmented reality applications for mobile phones, except that it's not really real-time, since camera shots are analyzed in the background after saving photos to the phone.
