This guy climbed the Eiffel Tower without a harness and recorded it on his GoPro in order to provide all of us with a good month's worth of nightmare fodder. His name is James Kingston, and he's a self-described "adventurer" who climbs a bunch of crazy stuff—including cranes in Dubai, the Wembley Arch, and chimneys in Germany. He did the tower climb last year with his photographer friend Esty, and just posted the video to YouTube.
