Those tuned mass dampers are huge and heavy and help limit a building's movement by swaying in the opposite direction of the building. That is, if the wind is making a skyscraper sway to the right, the damper will sway to the left to dissipate the kinetic energy, and reduce the, um, swaying. What's interesting is that the Burj Khalifa, the world's tallest building, doesn't have that.
