Before we proceed, I need those of you using Vista to download our new Vista gadget. Previous one had some problems getting new images and was often left blank, but this new version (7.1) should work flawlessly. However, before I make it featured article, and spread the news more widely, I need you to place it in your Vista sidebar and see how it behaves in the following days. You can get it from the current link in the sidebar (“Vista gadget”). This new version is 7.1 After few days I’ll be checking in with you to hear your impressions. My belief is that there will be no glitches this time.
I find myself really completed when I finish an in-depth article like yesterday one was. The results are obvious, and can be seen in the comments section. When the topic is heavily researched, and provided images match the text perfectly, comments become more serious and interesting as well. I have enjoyed reading them all, and to answer Y-Man: off course I’d be interested to post your opposite images that only color blind people can read. It would be awesome to see how we are blind to them, and would probably put a smile on a color blind person’s face!
Lately I’ve been thinking more and more about migrating this website to WordPress platform. I think I manged to solve all the problems that could arise, so that the change is transparent to you. I have already contacted very good hosting company, and found out how to transfer all the links and content so I don’t loose any SEO juice or visitors. I just need to find some good designer who can make recognizable and unique WordPress theme for this site. If you know someone that would like to do it as a fan, or for money – email me. Before I conclude this post, here is another awesome illusion sent by Marcel Lafortune. I can’t believe this wasn’t photoshoped (probably was…). Oh, I will probably be minimizing the number of links in the future articles, and place only important ones. Starting today. Let’s hope that pageview count doesn’t drop.
Sometimes, optical illusions can serve a purpose. These images might seem familiar to you; look closely. Do they remind you of anything? If you have a driving license, or attended a medical exam at some point in your life, there is a big chance you encountered these during the process. Attached on your left, and below you may find some examples of color blindness test used for testing if person is partially of fully color blind.
If the numbers don’t jump out at you immediately, if you have hard time distinguishing the colors apart, or if you aren’t able to easily distinguish at least a vague guess as to what the number is, then you my friend are unfortunately – color blind.
A version of this test can be seen used in the film Little Miss Sunshine, in which a small girl is playing with the vision test chart with her brother. He is not able to see the numbers, or tell the different colors apart well enough to distinguish the numbers. The boy’s goal was to be a pilot, so when he is made aware that he’s colorblind, the poor kid has a small nervous breakdown. As we already stated, color blindness, or color vision deficiency, is the inability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of the eye, nerve, or brain damage, or due to exposure to certain chemicals.
Before we proceed onto our next example, here is a little history lesson: The English chemist John Dalton published the first scientific paper on the subject in 1798, “Extraordinary facts relating to the vision of colors” after the realization of his own color blindness. Because of Dalton’s work, the condition is sometimes called daltonism, although this term is now used for a specific type of color blindness, called deuteranopia. Below you may see the example how one that is colorblind can’t distinguish the numbers on the card. Don’t be mistaken, color blind people don’t see everything in black and white, I just gave this as a guideline so you can understand their inability.
Color blindness is not the swapping of colors in the observer’s eyes. Grass is never red, and stop signs are never green. The color impaired do not learn to call red “green” and vice versa. However, dichromats often confuse red and green items. For example, they may find it difficult to distinguish a Braeburn from a Granny Smith and in some cases, the red and green of a traffic light without other clues (e.g., shape or location). This is demonstrated in this simulation of the two types of apple as viewed by a trichromat or by a dichromat.
In certain situations, color blindness is classed as a disability. However, color blind people have some advantages over people with normal color vision as well! There are some studies which conclude that color blind individuals are better at penetrating certain camouflages.
On your left, you may see another color vision test card. This one is pretty hard, as some individuals with perfect vision may have problems seeing the number inside it – it is 56 if I’m not mistaken.
Hope we learned something useful today. Before I conclude this article, there are some more vision test examples for you to enjoy:
And then some more… Examples below are much bigger in size. If you had no problem recognizing previous numbers, but have more problem distinguishing these, don’t be afraid – it has nothing to do with color blindness. Probably its just that your eyes can’t capture the whole image at once.

So, I’ve been to my friend’s wedding yesterday, and it was more fun than I thought it would be. Usually I’m kind of a sociopath at simmilar events, but this one was so relaxed and spontaneous, I’m actually glad I attended it. As I explained on Friday, this was the reason I missed posting a regular illusion yesterday. Only now I realize how I could have made an auto-post like before. It is a new option on this site, so I forgot all about it. To redeem myself, I’m sharing this nice optical illusion which is more than great, if you ask me. When you manage to solve it, please hesitate from flaming… I can already hear all those puritans, saying how offensive it was to them, and that there are kids out there watching this site. My response: it’s just a simple word which can be found in all the dictionaries around the world, so before you complain, be sure to forbid your kids to read, and prohibit them to answer which gender they are when asked. If this still wasn’t enough… you missed an “E” in front of the solution. All these hints should be more than enough for you to solve the mystery, but if they weren’t, take a closer look at the title, and remember this ;) About the exam, the results are coming on Monday, at least I hope they will.
Lucas Braun discovered three new optical illusion samples, one of which we already posted years ago. Let’s first give Lucas a chance to express himself: “Hi Vurdlak, I love your website! It is incredible how you manage to post a new amazing optical illusion almost every single day. Your daily commentaries are what really give the site character though. I wouldn’t keep coming back if the sight was all just pictures. Here are some illusions I found today. The first two are by London based Illustrator Claire Scully, and can be found below.”
Now, after reading how awesome this website is, and how great person I am, we can continue deciphering following images. I don’t have much time to spot all the hidden stuff they contain, but I bet there are more than few illusions present here! Can you spot them all? Btw, I’m waiting for my exam results to appear, and will be attending friend’s wedding tomorrow, so probably there will be no updates on Saturday.
I constantly receive requests for more stereograms, either though my mailbox, or inside the comments section. My problem with seeing the hidden image they contain is probably the reason I posted only so few of them. Magic Eyes, or how some like to call them “stereograms” are pictures you have to concentrate at, and suddenly the hidden meaning pops out at you. With the later mentioned, sometimes there is no hidden meaning, just the option to see the 2D image in 3D. Probably later versions aren’t stereograms at all, instead they should be refereed as stereo images. I’m the guilty one for posting them all inside the same category. If I understand your help correctly, you have to try and focus on the illusionary dot few inches behind your monitor, which I never manged. If you see this example, along with its solution, this is how the result should look like (apparently). Now let’s solve these three without me! If you want to see more of these, use the search in the sidebar, and enter stereograms or something. You can find more inside the appropriate category. Btw, the M&M Man is courtesy of Gary W. Priester.
We already had a chance to meet Elena Moskaleva through one of her previous works entitled “Kindness“. Well, this time Elena is back with two of her new artworks entitled “Happy Day” and “Metamorphosis”. Which one did you like better? Can you easily see the illusions Elena has so nicely integrated into her works? I like all three of them, except it would be much nicer if the optical illusions they hold were a little different each time. This way, it’s like seeing the same picture, only in blue shade. Two more days till my exam, and I have lost my most important script – the one with the previous exams including answers. How much of a jinx am I?
As I already explained, this week will be a killer. Not from the illusion point of view, but me studying my ass of. Due to this situation, I have composed this post yesterday and set it to auto-publish itself today. How cool is that? About those fish oil pills that are supposed to improve your memory, I decided to avoid them for now, as I’m not the biggest fond of any kind of pills and medicament.
On your left you may see another known example of parallel zebra lines. As hard as it may be to imagine, both vertical sticks you see are perfectly straight, and mutually parallel. The strange background pattern is the guilty one for making them look they are leaning. Another interesting example can be seen below. Can you believe that all these snake-sampled lines are perfectly straight and parallel? No? Well, I’m just messing with you this time :) Had to test how strong my influence rally is. Enjoy your stay, and keep your fingers crossed for me passing the exam on Friday.
As I was just about to give up, I found this interesting optical illusion to share with you today. There is nothing complex about this Wonky-Tonk building. It has it’s roof, doors and four windows. There are also two of the tenants in front of it… but wait! Why are the tenants so upset? Apparently they are puzzled by the upper right window of their house. The landlord explained to them there is nothing wrong with it, and that the both upper windows are exactly the same. Although they wouldn’t be much satisfied even if the windows were completely identical, but they are still puzzled how his statement can be true? It is more than “obvious” that the right window is leaning much more to the left, than the left window. Is it possible that the landlord was right? Let’s try and prove this: if you remember the leaning tower optical illusion that won the 1st place in 2007 optical illusion contest, you will see where this goes. Jump inside the article to see the further proof:
If we highlight and paint the right window in red, then cut it from the original image, we can easily move it around the house. What I did next, I made this slice semi-transparent and placed it over the left window. I have to admit I was too shocked when I saw that both windows overlap perfectly. How did the landlord know this from the beginning? Did he construct the building this way on purpose? This is for us to ask, and for landlord to know.
