Optical Illusion of The Day: See Your Little Ones Grow! |  |
| Posted: 20 Oct 2011 04:27 PM PDT I have just received this optical illusion from my former classmate – it’s a promotional poster for some sort of product called Horlicks. I’m not gonna tell you what the the illusion here really is, as I have confidence you’ll manage to spot on your own. I’m sure you will find it sooner or later. Yet, there is a chance you won’t like it as much as I did (which is mostly because it managed to fool me when I first saw it). The only hint I can give you is this: if you think you’re seeing a hand holding a magnifying glass, think again! BTW, I was surprised how no one answered my earlier question :( !?

Check this out: wait for the warping animation below to get running. Then, when you cover up the center of the image with your hand (just like in the example showed on your right) the dots will appear to speed up. On the other hand, if you cover up the edges the dots will appear to have slowed down. Now if this isn’t illusion, I really don’t know what else to show ya’.

| Just What Do You Think You’re Doing, Dave? Posted: 27 Sep 2011 06:35 AM PDT Seeing our latest illusion, I was immediately reminded of Hal 9000 and his memorable voice addressing Dave Bowman in 2001: A Space Odyssey. I won’t talk about how great this movie really was, and how it marked the whole era, I’d rather see what you think of the illusion attached below. By now you must have noticed it has something to do with our recent Psycho post. After my initial disappointment (having read your feedback), I learned that my previous pick just didn’t do justice to the whole cinemagraphs story. I learned how I failed in choosing the right representative to start this whole new category with. I just hope today’s sample will change all that. If you have time, feel free to read my thoughts on this from couple of days earlier.

| Meteor Crater Optical Illusion Posted: 23 Sep 2011 07:43 PM PDT Here’s an illusion I received from Alexis Monnerot, which was just finished on the morning 21st of September. Located in front of the Montparnasse railway station in Paris, France this hyper-realistic 3D chalk drawing greatly reminds one of Julian Beever and his epic installments. I’m not exactly sure about the author behind this installment, but I’m sure Alexis will enlighten us in her comments! And as we mentioned comments, remember how I recently improved the discussion section with the ability for you to add pictures inside them? Well, as of recently it seems you have started using this option much more frequently. It provides me with great joy to see how people began contributing more intensely. For example, it seems there is a new trend among you – outlining solutions and posting related illusions directly inside your comments! This was my intention in the first place when I originally imagined this website! If at some point in the past you have asked yourself how come I rarely post solutions to the illusions – I secretly hoped in time our community will evolve and start contributing by itself. Seems we are on a right trail of reaching this right now. My next idea would be to add some kind of voting system to your comments, so that the best voted comments would jump up first. In time, I imagine it would come to that, that a particular comment holding the solution (image attachment or related illusion pic) would rank best. What do you think of this idea? (Just me brainstorming out loud…)

One thing that surprised me was your reception of our recent cinemagraph illusion. I thought you’ll be astonished, mesmerized, surprised even, yet it seems I was wrong. The difference between simple animated .gif files and cinemagraphs is not easily distinguishable. However, having more luck than taste, seems I wasn’t so wrong after all. Some of our users noticed that this “Psycho” illusion holds another well hidden easter egg inside it – a frame featuring some sort of skull-ish X-ray layer, one that isn’t so obvious. Have to admit, I never noticed this before! It’s such a shame you didn’t react positive on cinemagraph illusions, as I had few of them lined up to be published soon. The beauty behind them should lye in the fact that only single detail gets animated, while rest of the photo stays just what it is – a still photo. Apparently it takes lots of time to create them. Check out this gallery and see if I can change your opinion ;D

But what I also think, is that it couldn’t hurt encouraging your little toddlers to try and construct something similar on their own! Not only will you motivate them to “mathematically” analyze the 3D space, they will also learn the beauty behind optical illusions, and educate themselves while doing it! When Escher chose to construct this deception, he placed the staircase on the roof of a building and structured the building to convey an impression of conformity to strong (but inconsistent) vanishing points. He has the right vanishing point higher than the left one.

| Mesmerizing Cinemagraph Illusion Posted: 17 Sep 2011 02:39 PM PDT With a little help from Jemish Dave, I stumbled across a unique technique that left me mesmerized. Ever seen something like this below? Quit reading this text and check the illusion attached. How long does it take you before you notice what it hides? After you checked the illusion out, you may PROCEED reading – don’t cheat!….. Has it surprised you? It may take some time for these things to load, and it also depends on type of connection and speed of your interface for the effect to happen seamlessly, though! If you want to know, these things are called cinemagraphs (little different than stereoscopic images we already showed). Creating a cinemagraph photo is not as simple as it may appear. Some of them took their authors entire day to make, but as you see the results are breathtaking. Cinemagraph is a technique of blending the effects of images and videos. Some of them can end up quite exciting, funny or extremely creative. It might take few seconds for them to fully load, so be patient and watch carefully!

Anyhow, I prepared two entertaining optical illusion constructions for you today. It’s nothing we haven’t seen already, but I believe how the beauty of both paintings makes them worthy showcasing here. Can you see the illusion yourselves? Can you see where one column starts and the other ends? I always liked this sort of illusions, no matter if it involved elephant legs, soldiers or pencils… Hope you will enjoy these as much as I have!

| Benham’s Disk Optical Illusion Posted: 13 Sep 2011 09:26 AM PDT
It was pretty popular back in the “old days”, as you could easily make your own unique spinner using nothing but piece of cardboard, a pencil and a toothpick! So what is so special about it? In 1894, toymaker Mr. C.E. Benham discovered that a spinning disk with a particular pattern of black and white marks could cause people to see colors! Mr. Benham called his disk an Artificial Spectrum Top and sold it through “Messrs, Newton and Co.” Benham’s Top (or Benham’s Disk) has puzzled scientists for over 100 years. Let’s see if the spinning black and white disk can fool you into seeing some colors?! Do you think you can understand why is this happening? At some point, you should also be able to see a radiation warning sign inside the spinner!

| Dancing Stars Optical Illusion Posted: 11 Sep 2011 02:57 PM PDT Let’s see what we have prepared for you today… User called Yep submitted an interesting picture in somewhat unconventional way – Using our recently added function (where you can now attach photos inside your comments) Yep proposed we publish “Dancing Stars” in one of our next updates. I’m not 100% sure if we had this one already, but you have to admit that the effect it provides is really memorable. Just like the Ouchi illusion from few days ago, dancing stars below start to wiggle as soon as your eyes begin to wander across the screen. BTW, notice how the rectangle shapes appear slightly slant, even though they actually aren’t?

| Posted: 09 Sep 2011 08:08 AM PDT Each time I post another item to our skull illusions section, I pledge myself it was the last time I did so (as they usually work in pretty much the same way). I fear if I over-bomb you with similar illusions you’ll soon grow tired of them, thus stop visiting this monumental website. However, running a decent “Skull Illusions” category wouldn’t be it without including this beautiful series of charcoal drawings by Tom French, an artist who has been greatly inspired by Charles Allan Gilbert’s optical illusion entitled All Is Vanity (1892). I promise, there will be no more skull illusions for some time now ;D Be sure to check Tom’s homepage for more awesome pencil drawings!

| Illusion Carpet in The Game Store Posted: 07 Sep 2011 10:45 AM PDT This optical illusion carpet, spotted in a Paris video game store provides an illusion of vortex floor. The effect is achieved by printing bent lines in according manner, just like what we have already seen in Apple exec’s garden. Not only does this carpet messes with your mind, it might also help you actually to trip while trying to walk across it! Can you see the floor on below photo as flat, which it actually is? Didn’t think you could!

| Posted: 05 Sep 2011 11:00 AM PDT I see some you have asked whether I have resigned from maintaining this blog, and whether Jill has been assigned as new editor in chief. Whether you like it or not I’m here to stay! It’s just that I was too busy over the last few days organizing a sport tournament, so didn’t have much time to work on new posts. This was only temporarily and this is why Jill’s work has dominated over the last couple of days. Everything should return to normal from now on, as my vacation is over and I’m back to business :D What could be better to start my shift with, other than new works of Milan-based artist Guido Daniele. Guido has created some gorgeous and fresh trompe l'oeil hand art! You’ve probably seen some of his early work on this site before, as well as ad campaigns he worked on! Hope you’ll enjoy these… For more samples, be sure to visit Guido’s official homepage.

| Coin Makes Big Things Look Small Posted: 04 Sep 2011 07:35 AM PDT We’ve talked about tilt shift images before, where the photographer uses selective focus and a titled shot angle or special lens to make a regular-sized image appear to be only a model. But the Big Money Project takes the tilt shift process a step further by placing ordinary objects beside a giant coin that immediately provides a recognizable miniature scale in our mind. The result is a delightful selection of every day objects that suddenly look unarguably tiny. The coin, made from painted and lacquered wood, was created at a 20:1 scale to an ordinary 50 cent Euro piece, meaning everything appears to be 20 times smaller than it is in actuality.
In the meanwhile, here are a few images showing what it took to make the original coin.

| Posted: 01 Sep 2011 08:06 AM PDT The Ouchi illusion is an illusion named after its inventor, Japanese artist Hajime Ouchi. It works in a way where the central disk seems to float above the checkered background when moving the eyes around while viewing the figure. Scrolling the image horizontally or vertically provides a much stronger effect. In this version titled “Ouchi Quintuplets” from author Kentra Gilbert, the effect is amplified even stronger! If you’re asking yourself what causes this strange phenomenon, well the illusion is caused by random eye movements, which are independent in the horizontal and vertical directions. However, the two types of patterns in the figure nearly eliminate the effect of the eye movements parallel to each type of pattern. Consequently, the neurons stimulated by the disk convey the signal that the disk jitters due to the horizontal component of the eye movements, while the neurons stimulated by the background convey the signal that movements are due to the independent vertical component. Since the two regions jitter independently, the brain interprets the regions as corresponding to separate independent objects (Olveczky et al. 2003).
