Escher inspired

Below, there are two photos of garage door of bonesetter in Chiba (Japan). The first image is a combination of endless staircase from Escher's artwork "Ascending and descending" and another Escher's artwork "Tower of Babel". The second is a variation of Escher's "Relativity".

Images are published here thanks to Nikita (Malfet_).

Homage to Escher
