I have the HBO artist series videos, the world's greatest artist videos (Monet and van Gogh) that are companion to the same books. I have several Calder videos, the Chuck Close, Up-Close video, Escher videos, Elizabeth Catlett, etc. etc. Most of the videos, I only show in 10-15 minute segments...for several reasons. I usually use them to illustrate a point or show examples of the artist work..or better yet...to have the artist him/herself talking about the creative process.
