[Thanks to Kirk]Remember Miniatur Wunderland, the huge railroad model in Germany? It's even bigger now. Includes hundreds of moving cars and even airplanes "taking off". The newest part is the airport, it's really impressive.
There are 260 people working on it, that's not a small operation. I have never even worked in a company with that many people.
(The voice-over guy is pretty remarkable in himself. I am not really sure if it's a very human robot voice or a very robotic human voice! :-)
