Maybe you know  that faces are more difficult to recognize when they’re upside-down and that sometimes we misperceived the facial expressions of upside-down faces .

But  Peter Thompson ,  from the University of York (UK) discovered an amazing optical illusion !

We can name it  The Fat Face Thin illusion. Your assignment is to compare the upside-down face on the left of the lower figure with the upright face on the right. Have you noticed how the upside-down version looks much thinner?! Moreover it appears longer shaped than the upright version. Of course, there is no need to mention how both pictures are identical. This illusion illustrates the internal features of the face (eyes, nose, mouth) can distort our perception of face shape.

Can you guess which nun is bigger?

In Milan , at the Porro showroom in Via Durini 15 , this Italian manufacturer is  presenting  new optical illusion inspired wall clock, designed by the Swedish designer quartet Front. The piece you see  is entitled: “Front around the clock”, and is made from a metal disk with a diameter of 55 cm. The numbers are applied perpendicularly to the base and are only legible by their shadows cast on the white surface.

When people first notice the clock hanging from a wall (example photo above this post), they don’t seem to notice what’s so different about it. Yet inspecting it from closer distance, made them smile and whisper “ah!”.

Aerol E. Catubag created this simple, but effective optical illusion involving colors! As Aerol explains, he discovered the illusion accidentally when trying to make a kaleidoscopic image. The illusion happens when you move your head back and forth. Watch the colors change their size, depending on your actions. For example, the blue box will seem to expand when you move forth, but the exact same box will shrink when you move your eyes further away.

By the way , I am not sure how many of you noticed, but when I talked about site upgrades – some of them are already implemented! You can now reply to other person’s comment, but what I’m even more excited to announce – now you can freely embed pictures in your comments!

In a  gallery of  optical illusions on Facebook,  one of the items that gained my attention was this Republic of Palau silver coin. The author behind Don Quixote motive (engraved on this coin) is great #Sandro Del Prete, and apart from the illusion, I was even more baffled with the Palau Republic.  I have never heard of Palau.  Oh, and the illusion should easily be seen, specially if you’re a Don Quixote fan, like I am…

Here’s a nice submission. This one was sent in by John Newman, who has seen this type of illusion hundreds of times around the net, but never in real life!
Remember when doing our duty, most of the time we let our thoughts slip by, and before you know it – illusions start appearing in front of our eyes! The thing is… do you see all those gray spots appearing at the white intersections below? They aren’t really there (just so that you know)…

If ever I’m so drunk I decide to shave your hair and make a tattoo on his head should be this. Or a rose in bloom. Yes, definitely will be a horrifying alien or a rose in bloom. Or a unicorn. Or a dolphin. Or a unicorn riding a dolphin (yes, someone already made one like that!). There are so many possibilities!
