Spiderman?

Alain Robert, the French climber who calls himself "Spiderman," crawls up the Abu Dhabi Investment Authority building in Abu Dhabi, United Arab Emirates, on February 23. While other famous urban climbers sometimes used clamps or suction cups, Robert uses no tools or safety devices. Using only his bare hands and climbing shoes, Robert has scaled more than 70 giant structures around the globe including many of the world's tallest structures.
