Art videos on youtube

I try to watch a lot of art history videos, interviews with painters, old Warhol flicks, what ever I can find on Youtube or on DVD'd to expand my "art knowledge". This past weekend I ran across this series produced by the BBC about the history of 3 colors of paint called "A History of Art in Three Colours". It was really fascinating to say the least. The documentary on Blue was probably my favorite 
Here is part 1 of the Gold 
and part 1 of the White 

If you have a favorite video please leave a link in the comments. I am always looking for new things to learn about.
