Quantum computers, which would rely on quantum mechanical concepts like superposition and entanglement to perform operations of unimaginable complexity, remain a pipe dream. But physicists have nevertheless come up with an algorithm that only quantum computers could use.

Behold the "Mandelbulb." This is a three-dimensional image created using the Mandelbrot set, a mathematical structure whose edges form fractals. The result is something that looks like an alien tree. Which isn't surprising, since fractals emulate patterns in nature.
