The World Trade Centers in New York will forever be a historic and painful part of history, especially in the US. Its destruction and the lives that were lost have become a sore topic in any conversation or endeavor.

Because its elevator ride to the 104th floor includes a 3D time-lapse video of the development of Manhattan's landscape in the past 515 years, which inevitably also shows the original tower come into view and fade into history.
