Let’s begin this week with a simple trivia: What do you think is the biggest problem for person updating this website (me)? It isn’t the content, nor writing. There is something else that gives me huge headache each time I’m on the road with my laptop. As I’m currently on vacation, I’m updating moillusions.com only when there is extra time for it. Still, I’m giving my best to ad at least one optical illusion per day.  Can you guess which factor bugs me the most in my work? I’ll explain tomorrow, but let’s hear your thoughts first!

Meanwhile, let’s check what Ben Heine has been up to. His gallery Pencil vs Camera, is interesting enough, but it still lacks illusory effects. Yet, there is this cat with pencil-drawn multiple eyes. If you remember one of our older posts, called Don’t Drink and Drive, you’ll quickly see the effect is identical (even though today’s picture is just a drawing). I was deeply amazed that simple drawing can give so much trouble to my brain/eyes.

I couldn’t resist sharing this optical illusion comic with you guys. The impossible figure is quite familiar, yet the comic is great. There is just one little favor I’m gonna ask you – Is there anyone among us, who knows how to decipher the artist’s signature (so we could give proper credit to him)? I think it’s Dave Copp-something…  can’t read the rest. Is it only me, or does the very same signature appear on almost every Garfield comic? Update – naaah, just checked this. Can’t believe I couldn’t remember it was Jim Davis who does Garfield

I’ve read couple of comments you left on our yesterday’s post, and it appears that if the left eye is enlarged in photoshop, some bluish dots can be seen, ones that aren’t present in the right eye. I believe this error appeared when I resized the image, and saved it in JPG format. Apart from that, the effect is real, and illusion works just like I explained. To make up, here is a similar optical illusion I found.

The watercolor effect inspired the wave-line illusion by Japanese vision scientist Seiyu Sohmiya. In this version, professor Akiyoshi Kitaoka shows that the white background behind the pattern is tinged by the color of the waves. It looks as if the orange wave has different background color than purple wave, while in fact both backgrounds are purely white!

This Japanese manga girl by professor Akiyoshi Kitaoka looks like she has one cyan eye and one gray eye. In fact, both eyes are exactly the same shade of gray. The proof can be seen right next to the original. The girl’s right eye appears the same as the turquoise hair clip, only because of the reddish context. Scientific American explains this optical illusion in following words: “Part of the process of seeing color is that three different kinds of photoreceptors in the eye are tuned to three overlapping families of color: red, green and blue (which are activated by visible light of long, medium and short wavelengths). These signals are then instantaneously compared with signals from nearby regions in the same scene. As the signals are passed along to higher and higher processing centers in the brain, they continue to be compared with larger and larger swaths of the surrounding scene. This “opponent process,” as scientists call it, means that color and brightness are always relative.”

Deep inside the woods, there is a clearing where one may see a forest goddess. But only if his heart is pure and will is strong, such sighting will be visible to him. Are your qualities enough? Do you qualify for this? Can you stand shoulder to shoulder with the chosen one’s profile, and see the forest goddess materializing in front of your eyes? Those among you having trouble seeing the goddess’s face, can purify their soul Forest Face Optical Illusion

As we reported back in Feb, scientists have been baffled by the appearance of a mysterious cave at West India Quay, London. Now the same phenomena has been spotted in Geldren, Germany. Moving away from fiction, stepping back to reality, what you see below is 3d chalk drawing created by Edgar Mueller for the International Street Painting Competition in Geldern 2009. This one is the second of his Cave Project Paintings. If you like what Edgar does, I recommend following #Edgar Mueller tag.

As we already once said, Donald “Rusty” Rust is an artist with a repertoire as extensive as his talent. Most of you will know him for his magnificent Hidden Tiger Illusion from our archives. This time Rusty painted another optical illusion, and once again your assignment is to try and spot the hidden tiger. Don’t be fooled by all those scattered pieces, rather concentrate on the big picture instead. If you’re still having trouble, use the widget or simply step few feet away from your monitor.

Wouldn’t bet my life on it, but comparing the styles used in both Invisible Neptune and today’s illusion – I think it’s safe to conclude that the author behind this one is great Sandro Del Prete again. Ne1 dares to disagree? Looking at the landscape, you’ll see some deer, few stumps and whole lot of everything, but how many of you have actually noticed the lil’-o-hidden lady? If you have problems seeing it, try looking at this through our very own optical illusion widget, and remember what we said about negative spaces…
