The most famous example of fractals is the Mandelbrot set. The Mandelbrot Set is the most complex object in mathematics, its admirers like to say. An eternity would not be enough time to see it all, its disks studded with prickly thorns, its spirals and filaments curling outward and around, bearing bulbous molecules that hang, infinitely variegated, like grapes on God's personal vine.
Fractal images are shapes showing self-similarities at smaller and smaller scales.
Before magnification, the size of most of the images on this site was much, much smaller than a grain of sand.
