I am stunned by the beauty and brilliance of this video by Spanish filmmaker Cristóbal Vila – Inspirations: A Short Film Celebrating the Mathematical Art of M.C. Escher.
M.C. Escher (1898-1972) was the Dutch artist who explored a wide range of mathematical ideas with his woodcuts, lithographs, and mezzotints.
The cool bloggers at openculture.com write: Although Escher had no formal training in mathematics beyond secondary school, many mathematicians counted themselves as admirers of his work.
