An Amnesty International anti-domestic abuse ad in a German bus stop is the first to use a camera to determine when someone is actually looking at it, allowing it to change the ad content as needed.
The ad portrays a husband beating his wife when no one's looking at it, but shifts to the couple looking happy when they are. You know, just like what happens in real life domestic abuse relationships. Well, except the wife in the ad isn't saying she "fell down the stairs" or "ran into a doorknob with her eye" to explain random injuries. (Hat tip to Julia!) [Coloribus via Copyranter via DVice]
