If imitation is the most sincere form of flattery, then this new interactive sign from IBM really, truly wants to get on your good side. It changes its appearance based on what the viewer is wearing.
The sign is part of IBM's Smarter Planet initiative, a broad effort to make worldwide systems more efficient with the use of technology. This billboard, using sensors and LEDs to dynamically update its colour, urges viewers to consider how technology could improve supply chain systems and retail experiences today.
As seen in the video, the sign works pretty well, matching colours accurately and updating quickly. It's susceptible to crash, however, when faced with processing clashing outfits. [Fubiz]
