The Eternal Scream

The Droste Effect is essentially a picture with a smaller version of itself within the picture. The smaller version of the picture would have even smaller versions of the same picture, and so on and so forth to infinity. Mathematicians call this self-similar recursion. These pictures can be as simple as a picture-within-a-picture-within-a-picture (ad infinitum), or can be as complex as to spirals into infinity by means of various transforms.
When put together, a complex Droste Effect picture spiraling into infinity can look very bizarre, very surreal and quite disorienting. But then again, the human mind isn’t built to recognize infinity.
