Now here is a great find, Dylan pointed out to me. I’m not sure if you’ve heard of the McGurk Effect before (I haven’t), but in short, it’s a perceptual phenomenon which demonstrates an interaction between hearing and vision in speech perception. In practice, this audio-video optical illusion effect may be experienced when a video of one phoneme’s production is dubbed with a sound-recording of a different phoneme being spoken.

Perhaps, it might be best if I just let you watch this short, yet professional video BBC produced. It explains the whole deal, and includes some real-life examples of McGurk effect in action. Have we just “discovered” a whole new field of optical illusions to be showcased on this site? Could be… BTW, it might take some time before the video loads. It’s somewhat large, comparing to our previous video illusions!

The art installation you’re about to see was designed by Peter Bristol, a lead product designer at Seattle-based product development consultancy Carbon Design Group. As author described it in his own words, “The Cut Chair” provides a stable place to sit, but creates an optical illusion that tells you otherwise. It usually takes few moments before people conclude how this trick works, yet the solution is pretty straight-forward. A plate concealed by a thick carpet allows a robust cantilevered seat. Three well placed leg “stumps” and the chair looks as though it has just been magically sliced apart. Peter is currently looking for a partner that would like to have the Cut Chair made for installation or production.

Let me see if I can dig up something I believe we haven’t already showcased before. It’s just that Sandro Del Prete’s paintings sometimes resemble each other so greatly, I can’t be exactly sure if I already blogged about this one. Either way, his transforming hands motive isn’t  something we haven’t already seen.

Still, take a look how seamlessly Sandro managed to differentiate figures shown on your right. What’s so interesting about it, is that when you focus on the figure on your left there’s no mistake it pictures a human hand. If you observe the right one, there’s no point denying we see a young lady holding her hands up in the air. Yet if you compare the two figures, it’s not easy to see any obvious differences. So how did he do that? It must be the surrounding context of each figure, if you ask me…

Looking forward to hear you ideas! If someone discovers this one was already featured, be sure to bring it up!

Strangely named user – BitPartDamaged, discovered two movie posters containing a “hidden” face. One is more obvious than not, and the other… heck, both of the faces are obvious! What is not so obvious is these aren’t faces at all, rather parts of the surrounding material that only resemble a human face. In first case we see a wrecked building, whose wreckage resembles a face, and in the other one – it’s all about photos and post-its Russel Crowe maniacally collected (in order to free his wife from prison, but this is another story…). Am not sure if the first poster for movie called “Carlos” belongs to Hollywood production, but I’m sure “The Next Three Days” is, as I’ve seen it few weeks ago. BTW, are we really incapable of establishing communication with Facebook (talked about the issue here) ?

Before we start discussing today’s post, there’s one semi-crucial thing I’d like to share with you… hopefully someone will be able to help, eventually (?!). As you know, little while ago we have started our very own Facebook channel, which over time has accumulated more than 8,500 members. Unfortunately, back then I wasn’t aware that once you set the title of your FB page, there is no way of changing it. So instead of just naming it Mighty Optical Illusions, we named it Mighty Optical Illusions – Photography Fan Page (clumsy, right?). I’ve heard that Facebook occasionally bends its rules, and helps prominent brands in this situation, yet I don’t have direct contact with anyone inside. It would be of great help if some of our readers knew someone inside, or even better if you actually work for Facebook to instruct us what would be the best way to fix this error, thus enabling us to promote our page further (currently, it turns out pretty ugly when you promote it via FB ads, as title can’t be changed).

Anyway, check out how perspective plays with us in the following photo! The soldiers appear so close to each other, yet the difference in their size suggest different! BTW, there is a bonus Easter-Egg animation called “Superman Experience” hidden somewhere inside this article… let’s see how many of you can find it ;D

Kudos to Marcin Ciślak from Krakow for discovering this amusing street performer, and taking a photo of him and then sharing it with our community! After some debate, we’ve concluded how these guys manage to fool us with impression they’re able to levitate. It all started with Johan Lorbeer and Flying Yogi. Remember those guys? Most of you probably missed them, as we blogged about the trick long time ago. So, let’s repeat our findings. How does the trick, this guy in below performs, actually works? It’s obvious he couldn’t  support his own weight just by leaning on the vertical pole, right?

Gianni managed to fool me with his submission, have to admit. What I first thought was nothing but interesting CG model of some sort of an engine room filled with pipes, turned out pretty beautiful optical illusion after all. Perhaps I didn’t gave it enough attention at first, or maybe I looked at the fullsize image from too close. Heck, this even made me wonder how many interesting illusions I skipped just because I couldn’t recognize their true nature. Anyhow, be sure to check the pipes below, and hopefully you’ll notice the hidden motive yourselves! Btw, shrunk version below should help…

Commentator who goes under the name Koaieus left an intriguing image on one of our last posts. Even though I prefer illusion submissions sent in through ordinary email, I suppose it can be done this way too. Anyway, this one was really hard to see. Can you spot the hidden motive beneath the layering stripes? It sure took some time before I could see it. Be sure to un-focus your vision, and lean to the side while observing the given example. If you’re still having hard time seeing it, check out the title – perhaps it might help!
