Iconic structures indeed. I didn´t know they were designed to be this eco friendly though, very cool :) Btw I hope the bad visibility was caused by clouds and not air pollution? Still some very impressive views from up there though! :)

Bad visibility likely a result of combination of bad lighting because of the cloudy sky and crappy camera/ camera skills! :) The view was pretty clear. And yes, like you, very surprised by the eco-friendliness of these trees!
