“The Story of Animation” by David Tart
The Story of Animation is a tongue-in-cheek “cartoon modern”-styled educational short that aims to introduce potential advertising clients to the animation process. The short was written and directed by animation veteran David Tart, and the animation was supervised by Magnus Moller of the Danish animation studio Tumblehead. And if you feel like you already know the animation process inside-out, then check out this short about how greeting cards get made.
