"The music"

Illusory black dots abruptly appear or disappear in white circles when we see the figure freely (= the scintillation grid illusion*1). On the other hand, the white circles disappear when we fixate at the center (the vanishing disk illusion*2,*3).

*3For the vanishing disk illusion, I think that Ninio and Stevens's paper might be the first report:
