Escher was a Dutch graphic artist who made mathematically inspired woodcuts, lithographs, and mezzotints.
His work is one of the more famous of the optical illusions to date. He was the first (if not only) artist I thought of when I thought of optical illusions.
He is the last artist from my initial ideas list, though maybe not the last I research. I like his work as it is interesting how he can get everything to fit so accurately and yet still look like a piece of art and not like a maths calculations sheet. Though he may be a bit over used in educational art projects. He is probably the easiest of the artists chosen to fit into the ‘Mind Games’ topic though one of the hardest to use in the project itself because his work is so complex.
