damper ball

This thing was interesting. Installed near the top of Taipei 101, it is a weighted ball that helps keep the building straight during high winds. info: http://en.wikipedia.org/wiki/Tuned_mass_damper

I had to look this building up. Wow.
This damper looks like part of a spaceship - I imagine it is massive.

Looks very Sc-fi like Doctor Who or something. Spotted it on your flashback post as it really stands out :) fav
