The wall are Static but appear to be moving
Focus on the + in centre, can you see Green dot? actually there is no such green thing rotating, its just illusion
The plates aren’t rotating, are they?
Focus in centre and the dots will disappear
Is the image vibrating? no its not
Can you feel the sickness of going back and forth? Just move your eyes to different points on this picture
Just an Illusion of moving bulge
