The ad is from Amnesty International, and I am just amazed at how appropriately they have used technology in order to convey their message against domestic violence.

Camera technology within the billboard works by scanning the nearby area and tracking eyeballs. When the person looks at the poster it shows a seemingly happy couple, however when their head is turned away it changes to the male punching the female. There is a slight delay in the picture changing, just enough to figure out what’s going on.
