I love the visuals, but the problem is in the first sentence: "two sources of excitation." That's not it at all.
If this were remotely true, then when I synced the oscillators on my synthesizer, the volume level would grow uncontrollably. But of course what actually happens is that the amplitude (approximately) doubles.
The problem is that the diagrams do not show what resonance actually is, but only what happens then the frequency of an excitation source matches the resonant frequency of a receiving medium, and in addition when the energy input exceeds the damping effect of the medium.
Nevertheless, it's still a great visual, provided the explanation is corrected.
