a phone for your focus
You've had staring contests with your friends in your younger days, staring contests with your dog in your stoner days, and now, you can have staring contests with their S4 phone, because it's capable of recognizing when you're looking at it. To play off that, they pulled a fun little stunt in public, inviting passerbys to stare into the phone for 1 hour while a bunch of ridiculously crazy crap happened in the background. If you could pull it off, you won the phone. Much tougher than it sounds!
