An optical illusion by Japanese mathematician and sculptor Kokichi Sugihara seems to have left netizens scratching their heads!
It was shared online by a Singaporean art director Tham Khai Meng.
Taking to Twitter, Meng shared a video featuring an arrow that he claimed can only point towards the right no matter how many times it is rotated.
“This arrow by mathematician and sculptor Kokichi Sugihara can’t point left,” he tweeted before disclosing the trick behind the illusion.
“Here’s how it works: It’s 3D-printed with a bunch of curves our brains don’t register,” he added.
The video shows that even after rotating the arrow 180 degrees, it still keeps pointing towards the right.
It did not take long for the tweet to go viral, with many trying to comprehend the optical illusion.
Since its video was shared online four days ago, it has collected over 2.7 million views on Twitter alone, along with thousands of comments and ‘retweets’.
