Successive Golden Rectangles dividing a Golden Rectangle into squares
(logarithmic spiral known as the golden spiral)
"A Sunday Afternoon on the Island of La Grande Jatte"
A Sunday Afternoon on the Island of La Grande Jatte - 1884 is one of Georges Seurat's most famous works, and is an example of pointillism. It is now in the permanent collection of the Art Institute of Chicago.
Seurat made several studies for the large painting including a smaller version, Study for A Sunday Afternoon on the Island of La Grande Jatte
(1884–1885), that is in the collection
of the Metropolitan Museum of Art, in
New York.
Georges Seurat
Georges Pierre Seurat (1859 - 1891) was a French Post-Impressionist painter and draftsman. He is noted for his innovative use of drawing media and for devising a technique of painting known as pointillism. His large-scale work A Sunday Afternoon on the Island of La Grande Jatte (1884–1886) altered the direction of modern art by initiating Neo-impressionism. It is one of the icons of late 19th-century painting.

Golden rectangle
A golden rectangle
is a rectangle whose side lengths are in the golden ratio,
one-to-phi, that is, approximately 1:1.618. A distinctive
feature of this shape is that when a square section is
removed, the remainder is another golden rectangle, that is,
with the same proportions as the first. Square removal can
be repeated infinitely, which leads to an approximation of
the golden or Fibonacci spiral.
Droste Effect
The Droste effect is a specific kind of recursive picture, one that in heraldry is termed mise en abyme. 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. This smaller version then depicts an even smaller version of itself in the same place, and so on. Only in theory could this go on forever; practically, it continues only as long as the resolution of the picture allows, which is relatively short, since each iteration geometrically reduces the picture's size. It is a visual example of a strange loop, a self-referential system of instancing which is the cornerstone of fractal geometry.
