Drawing on the classical elements of Escher's previous paintings, the work uses space distortion and positive and negative transformation to create visual illusion. Before the 20th century, many paintings constructed the three-dimensional space effect on the two-dimensional plane, so as to make the viewers "immerse themselves" and achieve the effect of "cheating the eyes". Painting is like a photographic description, and this kind of painting can be called reproduction painting. When we face these paintings, we can automatically recognize that the paintings are plates, cups and so on. What Escher's paintings destroy is our simple understanding of representation. This repeated transformation from two-dimensional to three-dimensional seems to be thinking about our space, and also seems to be asking: where do we come from and where are we going?
