Escher Hyperbolic

Escher poincare hyperbolic disk

Hyperbolic Disc with Escher. Base IH28
Since Escher, it seems that no one has created a hyperbolic tiling without the help of a dedicated computer program.
And these tilings are mostly taken from Escher's drawings.
This one, not only was created without a computer program but is impossible to reproduce with.
It is, moreover, created in vector while those resulting from program are in pixels.
