A new Wall to mark 20 years since the opening of the Berlin Wall

The German Embassy in Washington has set up a special Facebook page to mark 1989:

The fall of the Berlin Wall 20 years ago marked the beginning of a new era in history. It was the end of the Cold War, the beginning of a fully united Europe and proof that peaceful change is possible, even in the moment when it seems most unlikely.

Among the usual Facebook type things it includes a discussion on the role of leaders in peaceful change, and a chronology on the Facebook "Wall" of the opening Berlin Wall in November 1989:
