A COUPLE of amazing optical illusions trick people’s eyes into seeing movement, even though they are both stationary.
One shows a large ball shape that appears to be shaking, except it’s not a video or GIF, so it must be completely still.

Moving your head from side to side or scrolling up and down a web page tricks our eyes into thinking it’s shaking.
Expert in visual illusions. Akiyoshi Kitaoka shared the trick on Twitter to surprised users, but warned that some people might feel dizzy or nauseated.
One commenter said that they “had to take a screenshot to believe it.”
“The human brain, the most complex known object in the universe, can’t tell if this damn jpeg is meant to be a gif,” another quipped.
The effect is called the illusion of abnormal motion.
Kitaoka also shared another wild illusion that shows a dark mist spreading out instead.
But then again, it’s a completely stationary image, so it doesn’t really change at all.
This is known as the Fujiwara illusion.
One observer likened it to a “spreading, evil blob of darkness” and said it was “almost creepy” to watch.
Another noted that it seems to expand when you squint.
