Interactive billboards can occasionally encourage more socially beneficial behavior than playing giant games of Pong. Case in point—this clever installation at London's Euston Station by JWT for the National Centre for Domestic Violence. The ad, which shows a man berating a woman, encourages passersby to visit a website on their mobile phones (or scan a QR code) and drag the man away. The series of connected digital boards works well with the message here, as the man is progressively removed further and further from his victim. It would perhaps be even more fun to make a game out of this, and blow the guy away with space lasers, though that would probably conflict with the anti-violence message. Via Mashable.
