M. C. Escher (1898 〜 1972) is a Dutch artist whose works are strongly mathematical.
Some are mathematical images of tilings, recursion, infinity, reflection, geometric process.
Others illustrate the concepts of the above.
While still others exploit illusion and human perception to illustrate the above subjects.
