THIS disgusting optical illusion is not for the faint of heart.
The animation combines still images to create the illusion of movement, resulting in a truly stomach-turning visual effect.

Aptly named “Chunder Thunder,” the mind-bending creation was a finalist in the 2019 Illusion of the Year competition.
It seems to bring to life the painting “Ships in a stormy sea” by the 17th Dutch sailor Ludolf Bakhuizen.
It was developed by Mike Pickard and Gurpreet Singh from the University of Sunderland.
A description of the illusion on the competition website explains: “A ship appears to be tossed in rough seas in a wild storm where waves rush and clouds race across the sky.
“With the hatches open, the crew experiences a roller coaster ride! However, this impression of wild movement is illusory.”
To create the illusion, the researchers created several versions of the image, each with elements slightly shifted forward.
They then added a flashing effect to make it look like the ship was rocking violently back and forth in the sea.
The researchers said: “The directional movement seen in this illusion is achieved through the use of positive and negative images and different levels of brightness.
“Visually, this prioritizes forward movements viewed to create the overall impression of continuous movement.”
Optical illusions are often just for fun, but they also have real value to scientists.
Brain puzzles help researchers shed light on the inner workings of the mind and how it reacts to the environment.
Dr Gustav Kuhn, a psychologist and expert in human perception at Goldsmiths University in London, told The Sun earlier this month that illusions are important to our understanding of the brain.
“We tend to take perception for granted and rarely think about the hard work that underpins everyday tasks, like seeing a cup of coffee in front of us,” he said.
“Visual illusions highlight misperceptions and provide important information about the hidden neural processes that allow us to see the world around us.”
It follows the release of a spooky illusion earlier this month that made the viewer feel like they were falling into a black hole.
