I have just read M.C.Escher:More Mathematics Than Meets The Eye by Sara Robinson in SIAM News, Vol 35, Number 8, October 2002. In this article, the author wrote "...He (Hendrik Lenstra) owns more than dozen books about the artist(M.C.Escher), two documentary videos...".
What are the videos mentioned in the article ?
I searched on Google for the videos but there are lots of short videos about Escher(not official...). Are there any official videos about Escher and his work? I really want to find them. I like watching scientific videos when I have lunch or dinner, I usually watch physical documentary films from BBC Horizons.
Please suggest for me some videos.
Thank for reading and sorry for my poor English.
