Authors and educators have frequently been frustrated by the inability of equations and graphs to properly convey the temporal qualities of dynamic systems. Digital animations have been developed to help overcome this frustration. These animations compare classical and quantum trajectories of a pulsed particle beam, a harmonic oscillator in the absence of external perturbations and a harmonic oscillator irradiated with a resonance electromagnetic field. These digital movies supplement and enhance several previous journal articles (1-6).
