Who said that there's no masters of tessellation art after Escher? Just look on artworks by Japanese artist Makoto Nakamura. Pay attention to areas of the image, which are filled with identical figures that show dolphins, sea gulls, flying fishes and other figures. Put together all these figures constitute complete image, which looks as a single whole and don't fall to pieces.
Like in Escher's "Metamproses" or in "Sky and Water" tessellated figures transfer from one to another.
Below you can see some other tessellated images by Makoto Makamura.
