If it looks like a roof and it’s sloped downward like a roof, it should act like a damn roof and have stuff freaking slide off it, right? Not when it comes to Kokichi Sugihara’s “Impossible Rooftop.” Even if you place a ball on top of this model house’s roof, it won’t roll off. Instead, the ball will break physics,…
Trompe l’oeil (literally “to deceive the eye”) is an ancient technique whereby a painter creates a visual illusion via a trick of perspective. French street artist Patrick Commecy is a modern master of this art form, working with his team of artists at A-Fresco to create huge, hyper-realistic murals on otherwise drab…
There’s an iPhone laying somewhere on this carpet. You have to stare really hard and probably scour every pixel of this picture and possibly stop blinking for at least four minutes in order to find it, but I promise you that it’s there. Jeya May Cruz dropped her iPhone onto this rug and basically saw her phone vanish…
I’m not blind, I can totally see that the square is moving. First, it tilts to the right side and then it tilts to the left side, like a seesaw of sorts. But it’s actually a mind-bending illusion that makes you think it’s moving.
What in the sorcerous hells is this? Kokichi Sugihara’s ‘Rectangles and Circles’ illusion is a mind-bending visual trip that turns squares into circles and circles into squares right in front of your face. Different shapes are placed at a mirror and what you see in front of you is totally different from what you see…
Just because you live in a cramped downtown apartment doesn’t mean you don’t want to entertain. So here’s a brilliant way to keep some extra seating around, without wasting precious floor space once all your guests have left.
If this feels like an optical illusion, your Saturn sense is dead on. The gas giant’s rings don’t crisscross at 90 degree angles. They do, however, cast shadows, a fact which the latest shot from the Cassini spacecraft illustrates beautifully.
In every one of these side-by-sides from artist Howard Lee (and there are ten of them), one is the real object and the other is just a hyperrealistic drawing. Some of these drawings look so real that it’s hard to tell what’s art and what’s not. It’s especially great because after we get fooled, we get to see how the…
Two well-documented sensory biases enter. One entirely new sensory bias leaves. This is what happens when researchers pit your eyes against your ears to see which one you’ll believe.
It’s all about the perspective. Well, it’s also a little about how easily our eyes can be tricked. Here’s optical illusion expert BrussPup pulling the old perspective trick on us by making us think something is real when it’s not and making us believe something is fake when it’s actually the real object. It’s a fun…
Human wetware is astonishingly good at pattern recognition and interpreting complex, noisy data, but it’s also painfully buggy. Mars is the red planet, except it really isn’t.
Want to see a gender-neutral face turn masculine? How about a neutral face turn friendly, or a sharp picture turn fuzzy? This brief video will take you through all the ways your brain adapts to a stimulus, until you see things that simply aren’t there.
This extraordinary image of an apparent floating city has created a stir among conspiracy theorists, but a well-known optical illusion is the likely explanation for the phenomenon.
The Delbouef Illusion is well known. It absolutely works on humans, but scientists wanted to see if it also works on monkeys. That’s harder to establish than it looks. How do you resist having illusions about your optical illusion test?
Some of these optical illusions from Quirkology are totally silly but there are others that are genuinely fun to do, especially to kids and/or drunk people. It’s like explaining how to perform magic tricks or also how to exploit the weakness that is the human eyeball.
Using the same science that makes fiber optics and modern communications possible, these ultra-flat LED lamps look like they’ve each got a shade attached to them, but it’s all just an optical illusion.
Super photorealistic drawings are always fun to see because they tickle your brain into thinking things that you know are fake could possibly maybe be real because they just look so similar. Here’s a drawing from Dino Tomic showing a leaf drawing with a pile of other leaves. It’s hard to tell which one is fake!
Hidden in the vast majority of typefaces is one of the most well-known optical illusions in the world. Can you spot the illusion, and can you identify the famous illustration that demonstrates its power over human perception?
Little cutie sure looks pocket-sized, though, right? This April 18 photo shows a (perfectly normal-sized, alas) monkey taking a dip at the Amazon Animal Orphanage in the rainforest near Iquitos, Peru, where it joined dozens of other animals recently rescued from animal traffickers and circuses.
