A little technical innovation and you have an entire orchestra of players where the oldest is a 30-year-old and the youngest is, perhaps, a few weeks old, and they are all mobile. As I said in the headline, literally! This brilliant video celebrates 30 years of South Korean company, SK Telecom. The music is the theme song of the company played in a way any of the world’s best orchestra would. It may not be able to beat the theme song of India’s Airtel but it is worth listening.
