Fractals in Technology

Computer graphics use fractals to render realistic mountains, clouds, and forests without modeling every detail. A few simple rules, repeated at decreasing scales, generate astonishingly lifelike fields. This is how movies and video games create procedural terrain.

Fractal antennas pack long signal-receiving paths into tiny spaces because the self-similar pattern maximizes surface area. Your smartphone likely contains a fractal antenna — the geometry of infinite repetition made practical in a device that fits in your pocket.
