Confetti Fall: Chaotic Flutter Dynamics (2D)

A falling flat piece of confetti does not drop straight down — its orientation relative to its own velocity generates lift and drag forces that produce a torque, and that torque changes the orientation, feeding back into the next instant's forces. This 2D simulation integrates that real, angle-of-attack-coupled flat-plate aerodynamic model per piece, so lightweight pieces genuinely flutter and heavier/larger ones genuinely tumble, purely from the physics rather than a scripted animation.
