sentient billboard, brilliantly creepy
You're looking at the future and it's filled with inanimate objects that can read our feelings . . . maybe even some day *gasp* our minds? Creepy, yes, but think of all the marketing possibilities: Sad? Try this antidepressant prescription drug. Tired? Order delivery from Seamless so you don't have to worry about dinner.
Navigating the possibilities of this crazy world is M&C Saatchi in the UK. They're testing billboards that contain Microsoft Kinect cameras that can detect a passerby's mood and change the designs and copy of ads it presents to them. Crazy!
