I feel pretty much the same as WWTDD on this one. But honestly I would have to try it, I might be hanging onto the side and shaking like crazy, but this has to be one of the craziest things to experience.

This is the new attraction at the Sears Tower in Chicago that is supposed to debut in June. It is a glass structure that extends just over four feet out of the building. It is only a half an inch thick, and holds you 1,353 feet above the ground.

Sure I might piss my pants trying to walk out there, but man I want to try it! Here is the full quality photo.
