Notes
A double pendulum is the classic small system with chaotic motion. Two copies run side by side from nearly identical starting angles, with a divergence readout that shows when their paths part ways. The equations are integrated with fourth-order Runge–Kutta at a fixed step, the trails are drawn on canvas, and every control is keyboard reachable.
