People are losing their minds over this circle-filled optical illusion

Yes, there really are circles there.

The coffer iIllusion appears to be nothing but right angles, but there really are circles in there.

Optical illusions are always fun to play with, but some can be particularly challenging on the old eyes and brain. It's fascinating to see how different people process them and how quickly or slowly—or sometimes not at all—people see things that aren't really there or see images hidden within other images.

Not to brag, but I'm kind of an optical illusion savant. It usually doesn't take me longer than a few seconds to see whatever it is people say they are seeing. But occasionally an illusion comes along that stumps me to the point where I wonder if people are actually lying about what they are seeing.

This rectangle/circle illusion is one of those.

It's called the coffer illusion and was created by Stanford University psychologist and vision scientist Anthony Norcia. The image is made up of a pattern of black, white and gray lines of various shades that create the illusion of rectangles. It's easy enough to see the rectangles.

What's not so easy to see are the 16 circles in the image. Yes, they really are there.

Take a look:

Seriously, at first my brain said, "Nope." How could there be circles? All I see are straight lines. Straight lines horizontally. Straight lines vertically. Not a single curved line anywhere in sight. How can there be circles if there are nothing but right angles in the image?

So I did what any self-respecting social-media-savvy person would do and started scrolling the comments to see if anyone explained how they saw circles.

(Warning: Spoilers ahead if you're still trying to see the circles on your own.)

One way to see the circles is to focus on the vertical bars between the rectangles. For some, that makes the circles suddenly pop off the screen.

For people who need more of a visual clue, someone broke it down with colored shapes, literally circling one of the circles.

Once you see them, it's pretty easy to switch back and forth, but hoo boy, does it take a while to actually see them the first time.

Why is that?

According to an explanation from a professor and student from the University of Sydney, the reason we have a hard time seeing the circles at first is because of our brain's strong tendency to identify objects in what we're seeing. The lines come together to form edges, contours and shapes, and our brains fill in the objects.

"For most people, the grouping into rectangles initially dominates," the authors write. "This may be because rectangles (including the ones we see in door panels) are often more common than circles in our daily environment, and so the brain favours the grouping that delivers rectangular shapes."

I figure it's also likely due to the rectangles looking more 3D (therefore like a real object) while the circles appear as 2D.

Aren't our brains amazing?

Airbnb host wakes his guest up in the middle of the night so she wouldn't miss the northern lights

Best. Host. Ever.

Pency Lucero taking in the Northern Lights

Seeing the northern lights is a common bucket list adventure for many people. After all, it ticks a lot of boxes—being a dazzling light show, rich historical experience and scientific phenomenon all rolled into one. Plus there’s the uncertainty of it all, never quite knowing if you’ll witness a vivid streak of otherworldly colors dance across the sky…or simply see an oddly colored cloud. It’s nature’s slot machine, if you will.

Traveler and content creator Pency Lucero was willing to take that gamble. After thorough research, she stumbled upon an Airbnb in Rörbäck, Sweden with an actual picture of the northern lights shining above the cabin in the listing. With that kind of photo evidence, she felt good about her odds.

However, as soon as she landed, snow began falling so hard that the entire sky was “barely visible,” she told Upworthy. Martin, the Airbnb host, was nonetheless determined to do everything he could to ensure his guests got to see the spectacle, even offering to wake Lucero up in the middle of the night if he saw anything.

Then one night, the knock came.

Daughter shares incredible 3D optical illusions painted by her father, who has aphasia

David Hollowell suffered from a traumatic brain injury in 2021, losing his ability to speak. Remarkably, he is still able to express himself through art.

David Hollowell pictured with his 3D art

For a little over three decades, David Hollowell’s professional life had been dedicated to art. In addition to working as an art professor, his highly acclaimed 3D illusion paintings were shown in prestigious exhibits. In 2018, the 71-year-old began taking his talents to a larger scale, turning his family barn into an immersive mural.

Then, in May of 2021, Hollowell fell off the roof of his home, resulting in a traumatic brain injury leading to aphasia, a disorder that affects a person’s ability to communicate through speech or written language.

Though Hollowell couldn’t access words the way he used to, his ability to paint detailed, mesmerizing images remained remarkably intact. And his daughter-slash-self-appointed-TikTok manager, Adrienne, is determined to share his work and his journey with as many people as possible.

Most people don’t know he studied dance as a child.

These days, we could all use something to smile about, and few things do a better job at it than watching actor Christopher Walken dance.

A few years back, some genius at HuffPo Entertainment put together a clip featuring Walken dancing in 50 of his films, and it was taken down. But it re-emerged in 2014 and the world has been a better place for it.

Australian in the U.S. says she thinks it's rude that Americans don't say 'You're welcome'

Who's being more polite?

An Australian woman thinks it's rude that Americans don't say, "You're welcome."

There’s been a growing trend amongst American Gen Zers and millennials to stop saying, “You're welcome,” after being thanked. Older generations may think the change is part of a more significant trend of younger people having more lax manners, but in actuality, younger people believe that giving a simple “OK” or “Mm-hmm” after being thanked is more polite than saying, “You're welcome.”

Recently, Australian TikTok user Tilly Hokianga vented her frustrations with Americans in a viral post entitled, “Things That Send Me as an Australian Living in the US.” A lot of the points she made were pretty typical for someone visiting the United States, such as there's too much sugar in the bread and too many options for cereal.

However, she also noted that Americans have difficulty saying, “You’re welcome.”

Mississippi meteorologist paused for a 'human' moment while reporting on devastating tornado

"Oh, man. Dear Jesus, please help them."

WTVA 9 News/YouTube

Meteorologist Matt Laubham prays for the people in the path of a deadly tornado.

Broadcasters who have to report on tragedies as they are happening have a tough job. On the one hand, they have to maintain their professionalism and inform the public of what's happening in a factual way. On the other hand, they're still human and sometimes humanity trumps the traditional perception of what's "professional."

Such was the case for WTVA meteorologist Matt Laubhan, who found himself live on the air staring at a radar scan of a deadly tornado as it moved towards the small town of Amory, Mississippi. He, more than anyone, understood the severity of the situation, and he did his best to convey that to his viewers.

"This is a strong, life-threatening tornado that's going to move either extremely close to Amory or in through the northern part of the city of Amory."

He added, "Y'all trust me too much," explaining that people sometimes take his predictions of where the tornado will go as hard fact, but the reality is that tornados can change directions at any time. "So Amory, we need to be in our tornado safe place," he said.

Rick Astley covered Foo Fighters' 'Everlong' and it's shockingly great

Consider yourself Rick-Grohled.

Rick Astley rocking his Foo Fighters 'Everlong' cover.

Rick Astley has to be the luckiest '80s musician on the planet. The whole "Rickrolling" phenomenon has given his hit song "Never Gonna Give You Up" a reach far beyond its natural life span, and kept the guy a household name far longer than he probably would have been.

(For those who are unfamiliar, Rickrolling is when you make someone think they're being sent to a website, but the link goes to Rick Astley's "Never Gonna Give You Up" video instead as a joke. It's a silly viral bait-and-switch gag that's been going since 2006.)

But what people may not realize, because his most famous song has become an internet joke, is that Rick Astley is actually a really freaking great musician. The man can saaaang and it seems he's only gotten better with age.
