Taipei 101's stabilizing ball

Apparently the Taipei 101 sits just over 600ft from a major faultline, hence engineers had to install a ball of this size at a cost of$4m. Too heavy to be lifted by crane, the damper was assembled on siteand hangs through 4 floors of the skyscraper. It can reduce thebuilding's movement by up to 40%.
