The visual shirt set makes you look "squint"

Optical Illusion is a technique commonly used in design and painting. In the absence of careful observation, viewers are easily fooled by images that "look so not so".

Using this, Dutch graphic artist Maurits Cornelis Escher - also known as MC Escher - created interesting illusion paintings that made viewers "not know which way."

His works are currently on display at the Dulwich Gallery (London).

The discrete effect is widely used by Escher in its works.Like the Bond of Union in 1956 - it shows that the two are almost in a discrete state, but are bound together.

One of Escher: Drawing hand's well-known works (Hand-painted, 1948) laid the foundation for the strange loop concept - the strange rotation and effect of Droste - a form of visual effect in art.

This bizarre image is a collection of many lizards (No 56 Lizard Works - Lizard - 1942).

Another version of the Lizard was introduced in 1943. The crocodile from the picture appeared, walked away and returned to the painting, forming a closed loop.
