"The music in the space"

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

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

<I thank Bernd for giving me beautiful panels and information>

*4For the vanishing disk illusion, they published the paper in Vision Research, where they called this phenomenon "blanking": new ! <June 16, 2004>
