Chained op amp integrators to solve damped simple harmonic motion equation. Acceleration is proportional to (-) displacement. Play with values. Think of pendulum, mass on spring etc. The 1Meg resistor corresponds to light damping as not much "velocity" is fed back to reduce acceleration. Hold the push button for a couple of seconds and then release to start.
