Hinazo Nekota works at a piano-tuning studio in Japan called Pianopia. He recently made a miniature version of it, and it is awesome:

The replica pianos remain faithful to the originals, and he posts photos so you can see them in their various stages of completion:

I don’t have other words except.. impressive.

I highly suggest you follow his work on instagram, or, if you read Japanese, his blog, where you can find many more pictures of his miniature work.
