Thoughts on creativity

I’ve just started reading “Creativity, Inc.” written by the President of Pixar. In it he speaks about watching Walt Disney every week on TV explain how he created his movies.
I came across this video of the Disney animators painting the same tree but the end results are all different.

“Each of these artists are right according to his own ideas.. the great painter has something to say; he does not paint men, landscapes or furniture.. but an idea.”

I just love how they start with a very rough sketch and add all the details to the trees at the end! Do you have any great creative youtube videos to share?
