The Fraunhofer Institute-the guys who invented MP3 and screwed the music labels as a result, which is why we like them so much-have a booth at IFA with their latest inventions. The best one is this stunning magic mirror, an augmented reality display that gets any piece of clothing and transforms its fabric in real time. Live, the effect was absolutely amazing, indistinguishable from a real mirror. I just couldn't tell the difference. I think she's a witch.
