Aizawa Spiral

A strange attractor is a region of phase space toward which a dynamical system evolves over time — but unlike a fixed point or a periodic orbit, the trajectory never repeats. It folds and stretches forever inside a bounded volume. The Lorenz attractor, discovered by Edward Lorenz in 1963 while modeling atmospheric convection, is the canonical example: three coupled differential equations whose solutions trace a butterfly-shaped manifold that has become a symbol of deterministic chaos. The Clifford and Aizawa systems extend this idea with different nonlinear couplings, producing scrolls, shells, and toroidal sheets. What you see in these images is not a sketch or a stylization — each line is the literal trajectory of a point obeying the equations, rendered at full numerical precision over millions of integration steps.
