THIS nauseating optical illusion is not for the faint of heart.
The animation combines still images to create the illusion of movement, resulting in a visual effect that really turns the stomach.
The mind-boggling creation, aptly named Chunder Thunder, was a 2019 finalist illusion of the year Contest.
It seems to bring to life the painting “Ships on a Stormy Sea” by the 17th Dutch sea painter Ludolf Bakhuizen.
It was developed by Mike Pickard and Gurpreet Singh of the University of Sunderland.
The description of the illusion on the competition website explained: “The ship appears to be being tossed about in a wild storm on a raging sea, with waves rushing by and clouds racing across the sky.
“With the hatches down, the crew experiences a rollercoaster ride! However, this impression of wild movement is illusory.”
To create the illusion, the researchers created multiple versions of the painting, each with elements slightly shifted forward.
Then they added a lightning effect to make the boat appear as if it was bobbing violently back and forth in the sea.
The researchers said: “The directional movement seen in this illusion is achieved through positive and negative images and different luminance levels.
“This optically favors the visible forward movements, so that an overall impression of continuous movement is created.”
Optical illusions are often just a bit of fun, but they also have real value for scientists.
The brain puzzles help researchers shed light on the inner workings of the mind and how it reacts to its environment.
dr Gustav Kuhn, a psychologist and human cognition expert at Goldsmiths University in London, told The Sun earlier this month that illusions are important to our understanding of the brain.
“We usually take perception for granted and rarely think about the hard work that underpins everyday tasks, like seeing a cup of coffee in front of you,” he said.
“Visual illusions highlight perceptual errors and provide important insights into the hidden neural processes that allow us to see the world around us.”
It follows the release earlier this month of a spooky illusion that makes viewers feel like they’re falling into a black hole.
