Strange Attractor

Definition:

An attractor in phase space, where the points never repeat themselves, and orbits never intersect, but they stay within the same region of phase space. Unlike limit cycles or point attractors, strange attractors are non-periodic, and generally have a fractal dimension. They are a picture of a non-linear, chaotic system. See: Attractor, Chaos, Limit Cycle, Point Attractor.
