Com'è l'effetto domino?

(Epa/Rainer Jensen)

A row of symbolic Berlin Wall domino stones fall in Berlin, Germany, 09 November 2009. Some 1,000 dominos have been painted and put up to form a 1.5km long array of dominos alongside the former course of the Berlin Wall between the Reichstag building, Brandenburg Gate and Potsdam Square. On the evening of the 09 November 2009 the fall of the dominos will symbollically reenact the Fall of the Wall 20 years ago.
