An Adventure in Color/Mathmagicland (1961)

This is a documentary created by Walt Disney himself, it is a pearl that should not be lost …
Walt Disney himself explains concepts that are still difficult to see around, and explains them with remarkable simplicity.
I have great respect for this Man, for the Disney that existed when he was there, I like to think that without his cartoons, much of the modern world could never have been born, including special effects and 3D graphics.
