AN AMERICAN academic has stunned the internet with a stunning “eternal diamond” optical illusion.
Arthur Shapiro, a psychology professor in Washington DC, posted the creepy effect on Twitter and people were blown away.

The Eternal Diamond Optical Illusion Confused People On Twitter

The diamond appears to move up, down, left, and right even though it is fixed in one position.
The illusion shows a pink diamond in the center of the screen that, at first glance, appears to flicker and move.
But thanks to an intriguing scientific principle: a diamond only appears to move, but is actually fixed in place.
ETERNAL DIAMOND
Professor Shapiro posted an impressive illusion with a challenge for the public.
His tweet read: “Eternal Diamond – A diamond remains fixed in one place but appears to move up, down, left or right.
“See how far you can be from your screen before the effect wears off.”
The post received more than 1,000 retweets and 2,100 likes and sparked a mixed reaction from Twitter users.
One user @Jonalert was so frustrated that he posted: “Enough to confirm that I’ve given up on this challenge.”
Whereas Discodesert simply said, “The diamond moves. You can’t say it doesn’t move.”
According to his Twitter bio, Professor Shapiro works at American University and is co-editor of the Oxford Compendium of Visual Illusions.
And as an expert in the field, the American apparently understands the science behind the illusion better than most, having co-authored an academic paper on the subject.
In it he describes the perceived movement of the diamond as “determined by the relative phases of luminescence modulation between the fringes and the background”.
But whether you understand the science or not, it sure is much easier to keep looking at the diamond on the screen until you think it stopped.
This latest optical illusion is similar to the reaction of two Venezuelan filmmakers when they posted a series of incredible illusions on their YouTube channel.
