Jigsaw Puzzles Golden Rectangles & Droste Effect

Click the figure below to see the index of online jigsaw puzzles.

Online Jigsaw Puzzle: Rubens, Portrait of Susanne Fourment

Golden Rectangles and Droste Effect
The Droste effect is a specific kind of recursive picture. An image exhibiting the Droste effect depicts a smaller version of itself in a place where a similar picture would realistically be expected to appear. It is a visual example of a strange loop, a self-referential system of instancing which is the cornerstone of fractal geometry.
