Today is the 20th Anniversary of the fall of the Berlin Wall, signaling the end of communism in Europe and a new beginning in the world. Today I found a great section on the New York Times website that has interactive features and many amazing photos of the wall, then and now. I encourage everyone to look at this feature as it gives a fantastic look at the events surrounding the wall and includes a great web interface as well.
