On September 11, we recognize a few sites designed well that make tribute to the events of last September 11th.
Cantor Families site is a great example of simple design with fast downloading and dark background, September 11: Bearing Witness to History is a great site by Second Story. Check out the Collection page for a great design interface. Another good site is actually a Kiosk, named September 11: My Witness, by Second Story again, this is only a small portion of the actual project, pretty cool.
