optical illusion

Prepare to get Thatcherized.

It seems that Adele is going viral once again.

Perhaps you’ve seen the image in question previously (it seems to make the rounds every couple of years). But in case you missed it—it’s Adele’s face. Normal, just upside down.

Only it’s not normal. In fact, when you turn Adele’s face right side up, what you notice is that her eyes and mouth were actually right-side up THE ENTIRE TIME, even though the entire head was upside down. So when you turn the head right side up, the eyes and mouth are now UPSIDE-DOWN—and you can’t unsee it. Do you feel like you're Alice in Wonderland yet?


Just wait. Things get even more fascinating. Especially because this optical illusion is over 40 years in the making.

Below you’ll find the Adele photo in question. Go ahead. Take a look at it. Then turn the image upside down.

Can't. Unsee.

Crazy right? And just a little terrifying?

As the Facebook post explains, this mind-boggling image highlights a phenomenon known as the Thatcher effect. Our brains, so much more used to recognizing faces that are right-side up, have difficulty detecting specific changes once a face is upside down.

Seeing that everything is more or less where it should be, our brains don’t notice anything out of the ordinary in Adele’s face until we turn her face back to a normal position.

The Thatcher effect got its name from British Prime Minister Margaret Thatcher, on whose photograph it was first demonstrated back in 1980 by Peter Thompson, Professor of Psychology at York University.

This demonstration was one of the first to explore just how facial recognition works, and certainly the first to suggest that humans (and monkeys, it turns out) process faces on a more holistic level, rather than by individual components like lips and eyes. Since its publication, there has been a wealth of research exploring how our brain takes in both subtle and striking facial configurations.

Funny enough, it was once believed that this illusion only worked on the Prime Minister’s face. But as Adele has proven, anyone can be Thatcherized.

This mesmerizing dance routine is a cultural phenomenon in China and with good reason

Hearing impaired performers come together in perfect synchronization to share a beautiful message.

Hi China/Youtube

Dancers emulate Guan Yin, the goddess of compassion

In a world full of jaw-dropping dance routines, the Thousand Hand Guan Yin manages to captivate like no other.

A large group of performers in identical golden costumes flow together in synchronized movement so seamlessly that it appears as though one entity with several arms is moving about space.

That entity is Guan Yin, a goddess of compassion who, according to Buddhist legend, will never rest in nirvana as long as any sentient being suffers on Earth.

Guan Yin is often depicted with a thousand arms, having an eye in the palm of each hand, to symbolize an omnipresent mother figure always witnessing the pain of humanity with endless amounts of mercy, extending out one of her many arms to lend a helping hand.

The performers emulate this with intricate, delicate hand gestures while standing very close to one another, resulting in a mesmerizing optical illusion.

But the dance in and of itself isn't the most remarkable thing about this piece—each of the performers are hearing impaired.


Renowned Chinese choreographer Zhang Jigang (also known for large scale numbers like 2008 Beijing Summer Olympics opening ceremony) created the piece with The China Disabled People’s Performing Art Troupe back in 1987 to further emphasize inclusivity and compassion.

Thousand Hand Guan Yin, dance, famous dances

The Thousand Hand Guan Yin is one of China's most famous dances

While the first iteration consisted of around 20 performers, that number has exponentially increased to between 60-80. Knowing that each of these dancers were able to sync up so flawlessly without relying on music really does make it all the more powerful.

Today, the Thousand Hand Guan Yin remains one of China’s most well known and most beloved dance routines. And thanks to the internet, we too can be inspired by its wondrous spectacle and important message.

Nobody can believe this image isn't Photoshopped or AI generated, but it's 100% real

You don't always need high tech to create mind-bending optical illusions.

"Gap" by Kenichi Ohno

Japanese photographer Kenichi Ohno has viewers scratching their heads with his seemingly doctored image of an egret stepping into shallow water. After receiving an honorable mention in the Nature in Japan photo contest organized by the All-Japan Association of Photographic Societies (AJAPS), the image went viral as folks tried to suss out whether or not it was the work of some kind of tech wizardry.


The photo, titled “Gap,” is in fact real. No Photoshop. No A.I. Just good ol’ fashioned photography know-how.

Taking a glance at the image below, it immediately looks as though the egret is superimposed against two different backgrounds. Or perhaps the colors were changed using editing software.

What sort of witchcraft is this?

However, in reality, the sun is hitting a wall (seen in the top right corner) at just the right angle so that the wall casts its reflection in the water. The wall is also yellow tinted, explaining the stark color contrast.

Still confused? Fret not. On its Facebook page, AJAPS provided a pulled-back photograph of the location, where the wall is clearly visible. Seeing the top of the wall and without the egret really puts things into perspective.

Okay..it's starting to click

That certainly helps, doesn’t it?

And if things still aren’t clicking, this diagram really differentiates the different elements at play.

Aha!

There. That makes sense, right? Phew. We got there.

You’re not alone. Folks online were just as baffled, intrigued and exhausted after finally figuring it out.

“I SAW IT! I SAW IT! I SAW IT AT LAST!” a person exclaimed on Reddit.

Another wrote, “Wowwwwwww…took me 5 whole minutes of shouting ‘wtf???’ Before I saw it. This one is really good.”

“It seems inexplicable until it clicks, and then suddenly you wonder how you could have seen anything but what it is,” wrote another.

Some people, even after figuring out how it worked, couldn't quite get their minds to believe it.

“After reading all the explanations I understand what it is…But I can’t bring my mind to reconcile this image,” one person commented.

I think this Reddit user pretty much summed up what we were all feeling in this statement:

“Brains are funny.”

On the contest website, AJAPS called the photo “amazing” and applauded its “strong impact.” Judges complimented the effort Ohno must have put in to be in the right place at the right time with near-perfect conditions (apparently this shot would have been impossible on a windy day).

“It teaches us that a small change can make a big difference in a photo. It's difficult to shoot nature when there are man-made objects, but in this case they play a good supporting role and enhance the photo,” the site said.

Indeed, make one small change and give the internet's most mind-boggling optical illusion to date. Well done, Ohno.

Watch "The Starry Night" come to life with this optical illusion.

Vincent Van Gogh's "The Starry Night" is one of the most recognizable and beloved paintings in the world. It was completed in 1889 and has been part of the permanent collection of the Museum of Modern Art in New York City since 1941. It is not up for sale, but if it were to go to auction there is a chance it could fetch as much as billion dollars.

Such a priceless work of art is perhaps a strange object for a parlor trick, but trust me when I tell you this one is worth it.

Whether they are oases in the desert created by heat shimmer, an elephant with an indeterminate number of legs or straight lines that look crooked, optical illusions can throw our brains for a loop. They can also be super fun, and an optical illusion that makes the "Starry Night" painting turn into a moving picture is most definitely fun.


The illusion, shared by Alex Verbeek on Twitter, involves two steps. First, you stare at the center of a spinning spiral image for 20 seconds, then you look at the painting. Staring at the spinning spiral isn't as easy as it sounds—it makes your eyes buggy and your brain hurt a little—but even if you don't do the full 20 seconds, you can probably get the effect.

Aim for staring at the center of the spiral for at least 10 seconds, then watch "The Starry Night" come to life before your eyes. (You have to click "play" first, by the way. The spirals need to be swirling.)

The effect doesn't last long, but phew. Our brains are so bizarre.

According to a 2009 study by Japanese researchers, motion in optical illusions is still processed in the brain the same way real motion is. So don't be surprised if the moving painting makes you feel a bit woozy, if you're prone to motion sickness.

It's hard to believe that Van Gogh's "Starry Night" could be improved upon, but here we are. Definitely a "moving" experience to share with your friends.
