Adding a significant touch to ad posters on the bus stops, Amnesty International has resurrected an ad in Hamburg, Germany, which is intelligent enough, courtesy its built-in eye-tracking camera, to know when you are looking at it. Does it somehow remind of the billboards that recognize gender? Because this ad is installed for an anti-domestic-violence, when you look at it shows a happy couple and when you look away, the man becomes ferocious and is seen hitting his wife. The transformation happens in sometime therefore the viewer gets the message all clear.
