Fantastic video of two people that sneak onto a construction site and climb 650 meters up the Shanghai Tower. The views are extraordinary, especially when they look back down to the fog or haze below them. They do not appear to be using hooks, just free climbing all the way. Looks like there were stairs for a good portion of the way, but the top is all on them. Several times I found myself truly immersed in the lurching back and forth as they climb out over the nothingness. Just a great video, worth the time to view.
Look at this picture from the video, just incredible:
