      Tricky indeed! โ˜€
      There is a distorsion on the left corner bottom ๐Ÿ˜ฎ
      (maybe a screen distorsion ?
      because there is not on the all half right part! ๐Ÿ˜Ž

        What I saw was a black circular thing encroaching at the upper left and some white dots in the squares disappearing as the thing got near them. I saw no distortion or other activity.
        Edit: and definitely no red grid.

        I take the slow, deliberate approach in my aimless wandering.

          Red grid is mine for explain the distorsion ๐Ÿ˜‰

          the dots disapear is real, there is not illusion inside for them
          It's just the explanation of the illusion
          I am wrong?

            Initially there are dots and the grid looks distorted.
            [if it doesn't get your eyes tested or your monitor re-calibrated]
            As the dots disappear the grid appears to regularize,
            but it doesn't change at all - it was always thus...........

              That's amazing. I've never seen such small chess pieces. They anyone notice there are too many pieces? Is that the illusion?

                        yes of course ๐Ÿ˜„
                        but take a "print shot" of the video, you will see that I said is also true ๐Ÿ˜‰
                        Draw a red vertical line and the see left corner bottom!
                        it's just not a perfect video ๐Ÿ˜‰

                        And the effect is also well known
                        groups of different colors(here white dots)afect other environment's color for the brain (blacks squares)
                        As these white dots are tricky positionned illusion can run ๐Ÿ˜„
                        Collapse them at each center of the black squares you will obtain another one ๐Ÿ˜‰
