A volunteer installs green plastic hares for an art installation by German artist Ottmar Hoerl at Nuremberg's central square, July 31, 2003. Some 7,000 replicas of the painting titled "young hare" by Albrecht Duerer, a famous painter of the 16th century who was born in Nuremberg, remember the 500th anniversary of the painting last year. The installation will be opened on Friday.
