are you happy or hangry?

we collaborated with JCDecaux and starcom to find an engaging way to share the joy of yoplait’s new yoghurt smoothie. using facial recognition software, this out-of-home idea created a value exchange anchored in whether the passer by was happy or hangry, two very real category need states. their attention was then rewarded with a voucher to redeem a yoplait yoghurt smoothie of their choice nearby.
