When Vadim Makhorov and Vitaliy Raskalov scaled the Shanghai Tower last year (see here and here) the Internet went nuts (the video alone has been viewed over 41 million times).

The notoriety inspired them to attempt an equally crazy climb of the Ping An Finance Centre in Shenzhen, China. When complete it will be the tallest building in China and second tallest building in the world (antenna spire 660 m/2,165 ft; roof 555.1 m/1,821 ft). You can watch the heart stopping video below along with some photos of the daring feat.
