// Showing the relation between the elliptical Kepler orbit (along which the
// 'planet' --- symbolizes as a blue point --- runs) and the linear orbit of the
// Kepler oscillator (along which the 'oscillator particle' --- symbolizes as
// a red point --- runs). Notice that the motion of the blue point is determined
// (up to a factor which is determined by the numerical value of the period)
// by Kepler's second law of planetary motion and that the motion of the
// red point is coupled to that of the blue point as by gears.
