Yes this is another 'which line is longer' optical illusion. And yes your right, they are both the same. But it is still amazing isn't it.

Male or Female Face Optical Illusion?

5/27/2015

1 Comment

 
Picture
It is quite a mystery to everyone, including scientists, how we can tell the difference between the male and female face. So which of the above pictures is male and which is female?
Most people say the one on the right is male and the one on the left is female. Fact is that they are the same picture just that the contrast has been changed. Crazy eh?

Wriggling Dots Optical Illusion

Picture
Scientists have discovered a new optical illusion that will screw up your brain big time. Focus on the red cross while the dots move. They are wriggling around, right? Wrong. All of them are moving "in straight trajectories and random directions without colliding." Via Sploid

A Thaumatrope Bird in a Cage Optical Illusion

Picture
A thaumatrope is a toy that was popular in the 19th century. A disk with a picture on each side is attached to two pieces of string. When the strings are twirled quickly between the fingers the two pictures appear to blend into one due to the persistence of vision

Blurred Trees Optical Illusion

5/19/2015

Picture
No, your eyesight isn't getting worse, these trees are in focus but appear blurred, it's an optical illusion. The trees are primarily Noble firs and are a part of the Weyerhaeuser Mount St. Helens tree farm. Their blurry appearance apparently stems from the symmetrical growth patterns that are primarily due to pruning and trimming practices used to produce high-grade lumber free of knots.

Up and Down Optical Illusion

5/17/2015

Picture
At first glance this animated gif doesn't look particularly unusual or much of an illusion. Just a view of a table in a corner panning up and down.

But when you find out that it is not four different views but the same picture just moving up and down, now it looks strange. 

The secret is that we have moved the picture up and down whilst keeping the wallpaper pattern at the same level and then cropping the top and bottom. - Spyman.

OK, so this guy isn't really a giant, if you look carefully you will notice that he is standing on a ledge up above all the people in the background. But it does make you look twice, doesn't it? Image source unknown

You will all remember the famous optical illusion dress that went viral recently. Well here is another, this time it is not a neural illusion just a clever cut against a similar background but I think you will agree it still gives a great effect. Source Pinterest
