As Animation Filmmakers, we rely on our imagination for a living. How cool is that! Albert Einstein once said that "Knowledge is limited; but imagination encircles the world." This is true, everything you see around you was conceived from someone's imagination. An artist had to design in before you could wear it, drive it, walk on it and live in it.
Imagination is accepted as the innate ability and process to invent partial or complete personal realms within the mind from elements derived from sense perceptions of the shared world.
