Watch This Mind-Blowing Cylinder Optical Illusion

I think I know too.

Still............................................that seems too simple.

it looks like something off an IQ test........if this is like this, that what is like XX?

Spoiler alert! The edges aren't what our minds make them out to be...

My mind was not blown so I want a refund on my time I wasted.

claim DENIED you started out with a defective mind to begin with

As Sheldon would say, maybe his mind was pre-blown.

OK, you're free to do what you wish for the next minute and seven seconds!

This is how it works!

The story behind the illusion:

"In 1980, Kokichi Sugihara accidentally created an illusion machine. The young mathematician was working on making a computer program that could assist his research in robot vision and computer-assisted design when he discovered something strange. The program was designed to interpret two-dimensional line drawings and generate their three-dimensional counterparts (the idea was for the 3D objects to recreate the 2D drawings when projected back onto a flat plane). But when Sugihara fed seemingly impossible 2D line drawings, like the illusions created by M.C. Escher, into the computer, it unexpectedly generated feasible 3D solutions."
