What’s got everybody yawning?
Sleepy morning commuters at a São Paulo subway station didn’t stand a chance against this billboard. The interactive sign featured a giant face which would yawn when commuters approached the sign and motion sensors were set off. Yawning being as contagious as it is, this naturally triggered a yawning epidemic on the platform. Enter the mastermind behind the stunt – Brazilian coffee brand Café Pelé – to wake everybody up with product samples for all.
