The exciting thing is that we pretty much know how this effect comes about. Briefly, motion is a reconstructed quality, inferred from the timing of incoming light signals. Neural response latency is a function of contrast, so one can create apparent (illusory) motion by engaging the same motion perception mechanisms via suitably chosen contrast gradients.

Eye movements refresh the cascade.
