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.
A lot of things can bother you while you're trying to work, but what about things that you only perceive as nagging? In Keyfleas, little lights follow your fingers around a keyboard like a swarm of fleas, and can create the sensation that something is nipping at your fingers.
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…
Two tiles, seemingly different colors from one angle are actually the same color in different lighting. I don't get it at all. What's the trickery here? Is it the shadowplay? The lights? The tiles? I don't know.
It's no David Copperfield, but in this day and age surely that's a good thing? Winner of the Best Illusion of the Year contest, this moving circle of dots tricks the eye into seeing changing color even when they're not.
Watching a real life version of Escher's Impossible Waterfall melts my brain. The more I look at, the more confused I get! Thankfully, the secret on how the whole illusion works is out. There's clear DIY instructions on how to make your own impossible waterfall on Instructables and that video above shows what's …

Using inspiration from the impossible fork, ClarkeHopkinsClarke Architects built this optical illusion bookshelf. The shelf looks cartoony and almost invisible but that's not even the real illusion, the real mind bender is that there are what seems like 4 shelves on the left side but only 3 shelves on the right side.…
Click to viewDid you know that simple optical illusions can make it seem like the progress bars on your file downloads are moving faster than they actually are? Here's how it works.
It's a big skull. No, wait, it's two people under an arch. Hold on, it's a skull again. Two very different images can be perceived in this trick picture and now we are one step closer to working out how the brain spontaneously flips between such views, with the discovery of what may be the relevant brain region.
You're cruising down the road, nearing a school zone, when BAM! Out of nowhere, a little girl chasing her ball across the street appears. Your heart races, you slam on the brakes, and then her image dissolves. What?
As a kid, I thought the cartoon world could mix with the real one—like in Who Framed Roger Rabbit. I don't think I was entirely wrong. Just look at this odd metal sculpture.
The Cell processor that runs the show on Toshiba's new Cell TV is usually found in high-end PCs (and most notably the PS3). Now it's invading your living room, bringing real-time 2D to 3D conversion hype with it.
This fountain, created by inventor James Dyson and inspired by MC Escher, has water flowing up a series of ramps. Or so it appears to.
Slightly less gaudy than the million dollar diamond encrusted phone, this Illusion line of phones from Goldvish is made of at least 140 grams of gold. Add to that, the handful of diamonds on the front, including what looks like the numbers on the phone spelled out in diamonds, we're going to say this will be quite…
