This post goes to the most inspiring architect on earth.
Terada Mokei is a Japanese Architect that created the "ARCHITECTURAL MODEL ACCESSORIES SERIES".
These are like plastic models in that you have to assemble them, so the design and layout of each part was painstakingly created so that the excitement of it is constant throughout the process of assembling them. Parts that can be properly assembled, exciting shapes that encourage assembly, and the precision processing of manufacturing, these three points are repeatedly recalibrated into prototypes until they are correct.
The question was how should the 1/100 scale be distorted, to bring a world to life. If you look at the 1/100 scale human figure used in the product logo, it is quite different from the figure of a real human. The figure is deliberately distorted so it will be able to represent the world in a 1/ 100 scale. So it becomes the rule to distort all the items in the 1/100 scale world in the same fashion. With that the representation of the world in 1/100 scale is complete.
It just takes a ruler, some glue and a lot of patience to realize these amazing scenes.
