We visited the Seoul Museum of History and one of the exhibits there was this miniaturization of the entire city of Seoul, down to the tiniest buildings and apartments.
The city is huge, like 10 million people and the local government is very aggressive in doing hi-tech projects like this one. The took satellite photos of Seoul to make this as accurate as possible.
Here’s a short video I uploaded on YouTube:
They spent about $1.2 Million to construct this 3D exhibit, hiring about 200 people over 2 years to re-create the city in scale. They used LED lights inside the small structures and placed a huge laser beacon on the ceiling to high-light certain sections of the cityscape.
