Giant dominos are placed along the path of the original Berlin Wall

Workers install giant dominos made by young Berliners in preparation for a ceremony commemorating the 20th anniversary of the fall of the Berlin Wall in Berlin on November 6, 2009. The ceremony, taking place on November 9, will feature over 1,000 giant dominos erected between the Brandenburg Gate and Potsdamer Platz, along a section of the strip that once divided East and West Germany. During the ceremony, these dominos will be toppled, symbolizing the fall of the original wall. UPI Photo/David Silpa
