Optical illusion makes looking at Van Gogh's 'Starry Night' a truly 'moving' experience

This is so trippy.

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.)

Want a larger version of the painting to try it out on? Here you go:

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.

Facebook user Savannah Root from Missouri stared at the photo above for hours before she finally figured out what it was.

Everyone that sees it either gets it right away or sits there stumped. The picture is so mystifying that after one week, it's been shared over 33,000 times.

Bizarre optical illusion has people either seeing a car door or the beach

What do you see?

Car door and the beach.

Ancient sage Obi-Wan Kenobi once remarked, "Your eyes can deceive you, don't trust them." Well, he's right, kinda.

Our eyes bring in information and it's our brain's job to decipher the image and determine what we're seeing. But our brains aren't always correct. In fact, sometimes they can be so wrong we wonder if we are accurately interpreting reality at all.

After all, our brain can only label things if it knows that they are. If you lived on a deserted island your whole life and a cow showed up on the beach, you'd have no idea what to label it.

The latest baffling image that's making people across the internet doubt their senses is a picture tweeted out by Twitter user nayem. "If you can see a beach, ocean sky, rocks and stars then you are an artist," the comment reads.

But some people who see it also think it looks like a car door. What do you see?

Beach or a rusty door?

If your brain told you the picture is of a lovely evening laying on the beach then you're definitely an optimist. But, according to the person who posted it, the photo is of the bottom of a rusted out car door. Not very romantic, is it?

Trippy optical illusion makes people swear a Coke can is red. It's not. At all.

Try to make your brain NOT see the can as red.

We know Coca-Cola cans are red, but that's not why it looks red in a viral optical illusion.

Optical illusions are wild. We can look at an image and swear up and down we see one thing, only to find out what we're seeing isn't what we're actually seeing at all.

Some optical illusions regularly go viral, like the not-really-two-dogs photo or the cat going up or down stairs drawing or the moving Van Gogh painting. (And we all remember the debates over "the dress," right?)

One that's making the rounds now is an image that appears to be a pixelated photo of someone holding a Coca-Cola can. The colors are muted, but the can definitely looks red.

But it's not.

In reality, the only visible colors in this image are black, white and teal (or cyan).

Seriously, zoom in.

Trippy, right? There's a similar version that uses a more stripey pixelation:

And there's another version made out of black, white and yellow that makes the Coke can appear blue (negating the idea that our brain is automatically making the can red because it's the color our brain expects it to be).

Again, no blue in this image when you zoom in. There's only black, white and yellow.

So what exactly is going on here?

It's the complicated way our colors work and the way our eyes perceive and process them in our brains. Here's how one Reddit user explained it when someone claimed the white in the Coke can wasn't really white:

"It is white. This is an example of simultaneous color contrast, a phenomenon that occurs when two adjacent colors influence one another, changing your perception of the colors. The cones in your eyes make it seem like it is pink. Cones give your eyes good color vision but can also play tricks with your brain, hence why from a distance, ie not zoomed in, the color appears pink and why you see the can of Coke as “red” even though there is no red in the image.

Essentially, the way your eyes see color in the first place is by contrasting it with other colors."

Another commenter verified that the white is, in fact, pure white. "The pixel color on the white is: #FFFFFF which means pure white. If there were any red in there we would see a variation on it like #FFFEFE. It is not a trick. It really is pure white," they wrote. "I too thought it might be a compression trick. Nope. Our brains just be weird."

Indeed, our brains do be weird.

Photographer and filmmaker Jared Bendis explained it in another way with a demonstration of the "Retinex effect," also known as color constancy. Essentially, because our eyes have to recognize color in varying kinds and amounts of light (otherwise how would we find food at different times of day), our brain is excellent at filling in blanks. How it works is rather complicated, so Bendis shows how it works using a photo of a bowl of fruit.

Our brains may be weird, but also very cool.
