It should be circular motions of a hundred spheres because a pendulum wave arises from the simple harmonic motion (SHM) of many spheres. The SHM must have a return point with zero velocity (swing back and forth). This simulation has no return point and is just a continuous move of a hundred spheres around a center. Therefore, there is no SHM and it should not be the pendulum wave.
