Various micro-unit art seen in microscopic photos such as the world's smallest toilet

The world's smallest toilet and nail with a length of 0.2 micrometer are micro art with unit of size less than millimeter. It seems that it is a work of a microscopic photography contest, there are things that I misunderstand.

Details are as follows.

The world's smallest toilet. I can not add it.

Sagrada Familia.

Big wave.

A sight like a desert.

I can not move chess.

The world's smallest maze. There seems to be a part which is not a maze.
