Have a Coke and a smile, and see it in LEDs

Coca-Cola’s recent digital campaign involved a 6,200-square-foot LED screen in the Plaza de la República, Buenos Aires, Argentina and smiling passersby.  The interactive digital activation, invited people passing through the Plaza to share their happiness with the city, using facial detection software to snap photos of passersby or people standing on a special platform for the occasion, but only if the software detected a smile, according to the firm.
