SPLITTING HAIRS

QR codes are finding their way into the world in ever more inventive ways. This was a stunt devised to promote a shampoo in Thailand. Volunteers and even a Thai celebrity had QR codes shaved into their hair and then went for a stroll around the city. When people snapped the QR codes they were taken to a website about the shampoo. If you measure success in numbers, then you could say this worked: it apparently reached 10 million people!
