The Droste effect is a Dutch term for 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. 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 exponentially reduces the picture’s size.
The images displayed in this poster are made by Josh Sommers. As he said, all the images are created using the Escher Droste effect formula and the software are called Mathmap and the GIMP.
