“In case you’re wondering how optical illusions work… There is basically a glitch in the system in the way the brain processes what the eye perceives. The eye sees what it sees, but because of certain traits of the image, such as perspective, the brain “sees” it differently. We can concentrate and identify the illusion, yet our brain still sends back the same information. Sometimes, a shift in our vision can change the illusion altogether.” – from source
Some of these will blow your mind. I love the green cylinder/ shaded squares one!
