Last but not least: He who laughs, loses
To demonstrate just how serious they are about taking breaks, JWT in Brazil built Kit Kat vending machines with facial recognition and launched a “Be Serious” contest.
The game is old, but always funny. Because sooner or later there will be laughter. Two opponents stare into each other's eyes with serious expressions. Whoever laughs first loses. Normally, the opponents sit opposite each other. In Brazil, JWT has connected them via intelligent billboards distributed in different parts of the city. Equipped with a camera, screen and facial recognition software, the machines noticed when one person laughed - and spat out a Kit Kat bar on the other side. A total of 5628 times. And for once, even the loser had something to laugh about. (hae)
