I believe that producing pictures, as I do, is almost solely a question of wanting so very much to do it well. (M.C. Escher)

M.C.Escher is love by mathematicians, people who love art and me also. A lot of people like his works and with a lot of good reasons. His fantastic drawings are beyond our imagination. He did in the paper what some mathematians had been trying to show us for a long time. His works with symmetry are really amazing and now you can try to do some with a funny toy for young boys called Escher Web Sketch. Great tool (works in Java, ok?).
