To commemorate the bombing 67 years ago of Rotterdam they decided to use searchlights around the area that was wiped out, just see the pictures in the link below

Rumour is that they want to make this more permanent, not complaining about that here....
The last time this many searchlights was used BTW was in the 1930's at Zeppelin field, nuremberg conference best shown in the film "Triumph of the Willing" by Leni Riefenstahl, spooky coincidence somehow.... (pic here: http://www.kubiss.de/kulturreferat/reic ... infeld.htm)
