Russian daredevil duo Vitaliy Raskalov and Vadim Makhorov of YouTube channel On The Roofs have teamed up with some of their friends to hack one of Hong Kong’s highest billboards. To achieve the feat, the duo took the lift to the top floor of the China Online Centre skyscraper, before going out onto the roof and climbing to the top of the giant screen. From there, they could access the computer which displays the traditional ads and switch it up to display the words “What’s Up Hong Kong?” Equipped with a change of clothes, the team quickly made a stealthy get away, seamlessly blending into the hustle and bustle of the street below.
