Look at this picture of Saturn. Can you see the biggest ring? Are you sure?
Steeply-angled sunlight creates a muddled mystery of which terrain are mountains or valleys in this early-morning scene. Only snaking fog shrouding the river reveals the secrets of the inverted topography.
This is not an optical illusion, but it takes advantage of exactly the same principles that make optical illusions work: Our eyes and brain don't scan reality like a camera does. Instead, the brain interprets external inputs, building its own reality. No spoilers, just watch.
It looks like the white dots in this optical illusion are all orbiting an imaginary point in space that, at the same time, is orbiting the center of that red circle. They are not. In reality, they are all moving in straight lines going from one side of the red circle to the opposite one.
When I started to watch this video I thought I wasn't looking at a painting but a high definition flat display that tracked your eyes, modifying a 3D model to give you the illusion of real depth. And then the magics finally get revealed. It's so simple and so damn cool.
What a tricky mind trip. Though it looks like this fixed gear biker is playing a video game or stuck inside a M.C. Escher drawing or a part of an optical illusion, he's actually riding on a real bike course made with real ramps and doing real jumps. It just looks crazy from our perspective
These four squares appear to move at different speeds, stopping and moving, waiting for each other in pairs. In reality, they are always moving at exactly the same constant speed. Seriously. I opened the GIF in Photoshop and used guides to measure it—in every frame, the squares align perfectly.
It may seem like this guy has a space-time bending black hole on his skull, which is about to swallow that guy's finger, but of course it's just an awesome optical illusion, created by artist Cory Ferguson, instagrammed by Geometry Chaos. If you have to get a tattoo, you may as well blow people's minds with it.
Look at these grey circles. They look bent, right? Like somebody put a ring in a vice and squeezed it? Actually, it's just an incredible optical illusion courtesy of @SciencePorn. Both circles are perfectly round. Really. No really.
In this illusion, a toy car seemingly appears from no where. How is that possible? Well, the car was always there. Really. It's a simple but masterful trick, the toy car is programmed to travel along a designated route while the red cards are shown off as a distraction. As one card is shown to reveal nothing behind…
As far as tyrannosaurus rex replicas go, this one seems pretty cheery. Sure, it has sharp teeth and claws but they look playfully toothy. One thing scary about it though: the head and eyes seems to follow you wherever you go. Like the paper T-Rex is watching your every move. What's scarier? It's not actually moving.…
One is dark, one is light. One is gray, one is white. These are obviously two different blocks with two different colors right? Wrong. The two blocks are the same color. Seriously, they're the same shade of gray. Just place your finger across the seam (where the blocks meet in the middle) to reveal the illusion. Just…
Scientists have discovered a new optical illusion that will screw up your brain big time. Focus on the red cross while the dots move. They are wriggling around, right? Wrong. All of them are moving "in straight trajectories and random directions without colliding."
It's disorienting to walk into a room where nothing is as it seems. Your doctor might be grimacing even though your test results are fine. Or everything might look normal in your house until you realize that there's a cable outage and your internet is down. But if everything were an optical illusion you would probably…
Not even Hollywood's most beautiful are inmune to our brain's faulty image processing. Liv Tyler, George Clooney, Brad Pitt, Gwyneth Paltrow, Halle Berry, Robert Downey Jr., Keira Knightley, Christina Hendricks—all of them turn to creepy monsters when you get them through this freaky optical illusion.
So, here are some lines moving like crazy. Stop moving like crazy, you lines! Oh, here are some squares. "Hello lines, let's all play nice together!" they say. Now everything makes sense. How did this happen? Eye witchcraft! Thank you for the squares, stupid!
Watch this video while staring at the cross in the center, and you'll see bulbous foreheads, gigantic noses and terrifying eyes. Watch it again while looking at the faces, and you'll see they're perfectly normal pictures of attractive Hollywood actors. What the hell?
I'll admit it, it's been nearly a month since I covered the Kisai Optical Illusion watch and I still can't read the damn thing (it's a schooner, I'm told). But Kisai's latest user-submitted design is actually quite easy to interpret—hint: it isn't Morse code.
