Escher and the Droste effect

 

Step 1: unraveling Escher's picture

The first phase of the project was to reconstruct the straightened Malta landscape from Escher's picture by using Escher's grid. Joost Batenburg produced these pictures with a computer program from the scanned picture and the grid of Escher.

The resulting Droste picture is preserved under scaling by a factor 256=28. You can view this picture as a cycle of 8 frames, each time zooming in by a factor of 2.
