This is rather longish, perhaps better suited for a classroom rather than the Intertunnel, but worth watching nonetheless. Back in the old days, before computers say, animation was a team effort with egos set aside. "The entire operation puts one in mind of a symphony orchestra, where men who are good enough to be soloists in their own right are thinking only of the effect they are producing on the whole." The last half of the video shows four animators as soloists, as they each paint their own interpretation of an old oak tree. Striking.
