      Some people reported that they did not see this illusion. It is time to examine it. Does this image appear to move?

          Thank you for your votes. I have confirmed that a minority of observers (6% in this case) do not see this illusion.pic.twitter.com/ofsorm2VpQ

          This illusion has always appeared in motion in the past for me. This morning, however, viewing it first thing after waking (and barely awake at that) it was static. After a few minutes, it is back to appearing in motion. Seems cognitively relevant. Maybe others can experiment?

          I think unknown eye movement might play an essential part.

          I saw it move the most when my eyes were focused on something else (i.e. the tweet just above yours). If I focus on parts of the image I can 'make it' slow down and even stop.

          Me too. I find if I attend to the boundary, I can 'keep it all still' for a few seconds. But it's an effortful business doing so. Also stronger effect when fixating just outside the image.

          It only moves when your eyes move. When you focus on one spot, it stops.

          It only does when scanning the Z-Axis

          Staring at the central column there would be a slight shift then stationary. Looking elsewhere varied the extent and speed of the motion.

          I do but I had to open up the image and tilt my phone for it to work. May not be mobile-friendly.
