A great YouTube video: M.C. Escher: Adventures in Perception
This is a 20-minute Dutch documentary released in 1971 that displays the work of artist M.C. Escher (1898–1972), described on Wikipedia as “a Dutch graphic artist known for his often mathematically inspired woodcuts, lithographs, and mezzotints. These feature impossible constructions, explorations of infinity, architecture, and tessellations.” The first half of the film shows a lot of his work accompanied by a dissonant score by Felix Visser. About halfway through, we see shots of Escher at work, with narration offering biographical information sprinkled with quotes taken from Escher’s own statements over the years.
