Return of the Skyscraper
I for one am glad to see this. For one, skylines of US cities were frankly becoming rather boring in comparison to those of Asia and to a lesser extent, Europe. I look forward to the time when America's cities are again shining examples of both engineering and creativity.
In addition, this shows that we, as a country, have only been strengthened by events such as 9/11 and we will not live our lives as the terrorists choose, but rather as we ourselves choose.
One of my favorites is this Manhattan condo by Spanish architect Santiago Calatreva.
