Twenty years ago today the Berlin Wall fell, uniting East and West Germany. Celebrations today include fireworks, concerts, and the toppling of foam dominoes painted by school children. Spiegel Online International has a great collection of historic images and coverage of the 20th anniversary celebration.  They also have published their interview with Lieutenant-Colonel Harald Jäger, The Guard Who Opened the Berlin Wall (in English).
