Since 1999, the SkyscraperPage Forum has been one of the most active skyscraper enthusiast communities on the web. The global membership discusses development news and construction activity on projects from around the world, alongside discussions on urban design, architecture, transportation and many other topics. SkyscraperPage.com also features unique skyscraper diagrams, a database of construction activity, and publishes popular skyscraper posters.
This photo was taken from the front door of Flashdancers. (I used to work across the street at 1675 Broadway.) FYI, David Letterman's office is on the top floor corner with the sky reflected in the window.
