Maybe the true nature of things is not something that can be seen at a glance.

If you look at the image above on the computer in front of you,

The figure on the left is an angry face, and the face on the right is a calm face.

But, please stand up and take 3 to 5 steps back.

Suddenly, they swap positions!!

This optical illusion was designed by Philippe G. Schyns and Aude Oliva from the University of Glasgow.

This proves that we may have never seen the true nature of things....
