Sorry for no updates yesterday. Still in rush and figuring which apartment to rent, so hope you’ll forgive. About today’s Poggendorf illusion – it is one of the most famous distortion illusions known. Although much has been written about it since its discovery in 1860, the underlying mechanism that gives rise to this effect is [...]

Hehe, just to clear some things – I live in Croatia so the law probably differs in your country. Now that we made this clear, I’d like to ask you if you recognize the mysterious symbols below? No, its not Japanese again. If you concentrate enough, you’ll manage to translate the following symbol-constructed message our [...]

I’ve managed to obtain some black and white test cards which are used in some sort of psychology test. You should be able to see quite fast what these images below represent. They can’t easily be misunderstood, so once you see them, there is only one possible answer. Well, maybe if you are VERY imaginative, [...]

So, in the lack of “spot the differences” optical illusions, I have added this one that took my attention. These kind of “illusions” appear rarely on the site, and only reason they do is because you like them so much (at least so I heard). We can hardly consider them illusions. Only reason is [...]

Hy everyone. For today I have prepared simple, yet amazing optical illusion (like I always do :) The Poggendorff Illusion is an optical illusion that involves brain’s perception of the interaction between diagonal lines and horizontal and vertical edges. It is named after Poggendorff, who discovered it in the drawing of Johann Karl Friedrich Zöllner, [...]

So, we haven’t had this type of “Spot The Differences” game in a while. Last one I can remember, was the one with the University Classroom. If you can remember any other, please remind me. You should see the photo of a NY street, with a Taxi cab in it. The image is full of [...]

Got this image recently, composed out of some strange “alien looking” symbols. If I had no experience with optical illusions, I would consider this nothing more than plain gibberish. But since illusions are something I consider “my expertise“, immediately have I remembered my “Eye Examination Test” – which can be found inside optical illusion Tests. [...]

Stephanie Jones mailed me this awesome flick! Let’s make her describe it herself: “Hi! I really enjoy your site, and when I came across this in my lecturer’s blog, I thought I’d better send it in to you. It looks like another version of the Leprechauns illusion you have. One of the most [...]

Hy people! I have just received this image from my brother via gmail. We had very similar mathematical optical illusion at the very start of this website, and I find this kind of illusions hardest to solve. Maybe this should belong to some new category called “Brain Teasers” or “Mighty Puzzles“, still we can probably [...]

This one has been circulating the net lately, so it would be shame if I didn’t share it with you guys as well. What is the story behind the picture below? The influence of culture and environment can have an effect on our visual perception – believe it or not. This theory was first [...]
