Chaotic system with fractal structure.

Complex pattern, sensitive to initial conditions.

Chaotic system with deterministic nature.

Massive gravitational anomaly pulling galaxies.

Cyclic pattern in dynamical systems.

In the mathematics of dynamical systems, the double-scroll attractor (sometimes known as Chua's attractor) is a strange attractor observed from a physical electronic chaotic circuit (generally, Chua's circuit) with a single nonlinear resistor (see Chua's diode).
