(WASHINGTON POST)  Ana Swanson — One World Trade Center seemed like it took ages to build. Not anymore. This time lapse video, which webcam company EarthCam pieced together from hundreds of thousands of high-definition images, condenses the building’s 11-year construction into just two minutes. The video commemorates the opening of the One World Observatory on the building’s 100th-102nd floors last weekend.
