Tech stuff of the day. Gett Coca-Cola: Second Screen Reinvented

Gett Coca-Cola: Second Screen Reinvented from Gefen Team on Vimeo.
"Working with Gefen Team, Tel Aviv, and tech startup DOV-E, the brand embedded ultrasonic audio signals (imperceptible to the human ear) into a seemingly normal Coca-Cola television ad. When the spot aired, the audio signal was picked up by the Gett Taxi app – even if it wasn’t open." via contagious.io
