1. Escher and the Penrose's Amy LeFevers

2. The Artist M.C. Escher was born in Leeuwarden, Netherlands on June 17, 1898. Escher suffered from many illnesses growing up, therefore missed a lot of school and struggled in his classes, yet he went onto art school in order to further refine his strongest talent. Even thought Escher did not have a strong mathematical education, he was able to take his visual comprehension of math in order to create many different forms of art based off of mathematical shapes. Some examples of shapes he use are: geometric distortions and, importantly, the Penrose triangle.

3. The Penrose's’ The Penrose triangle was created, for fun, by Roger Penrose and Oscar Reutersvärd. The pair decided to entertain themselves by creating this impossible triangle. Later, Roger and his Father created another impossible shape. The other shape created was the impossible staircase. Lionel and Roger Penrose created a staircase that appeared to have no bottom stair, when fallowing it clockwise, or no top stair when fallowing it counter clockwise. The article written about these two shapes was published in 1958 in the British Journal of Psychology. Well, the article was showed to M.C. Escher, and the two shapes were used to create his two most popular prints.
