 Today we have a video of the French spiderman Alain Robert. This guy just walks up to the building and starts climbing up it without any safety equipment (helmet, rope, anything). His most recent feat that I know of was when he climbed Taipai 101 (the worlds tallest building) on December 25th 2004. In the video he just hangs on with his fingers and probably some special climbing shoes. In the video we link to here there is actually some film from someone inside the building the guy is climbing looking out at the guy as he climbs past the window.
