This Google Earth 3D model by "USS Voyager" gives a clear picture of the memorial in New York to open next week on the tenth anniversary of the 9/11 attacks.
A very nice remembrance video about 9/11 below. The narration is by a New York firefighter who lost a son in the building collapse. The son was also a firefighter.
Athinaios' 3D model of the in-progress One World Trade Center (formerly the Freedom Tower) is quite beautiful, especially when viewed in Google Earth.
