This work seeks to define the creative process in the cinematographic animation, inside its spontaneous and intuitive nature, not always deriving from rational deductions. Animation and Design are compared in its holistic and multidisciplinary characteristics, which favor the use and acknowledgement of intuition in their processes. Animation is characterized as the human faculty of analysis and synthesis of movements, which has been demonstrated far before the invention of cinema. The techniques and processes presently used in animation are then described and classified according to bibliographic sources. From these fundamentals, a definition for Spontaneous Animation is searched, with the help of the biographical reports on three great masters of animation: Norman McLaren (1914-1987), Fernando Diniz(1918-1999) and Len Lye (1901-1980). Four well succeeded didactic initiatives in animation are described: the Animathon (animation marathon), the Open Studio of the Anima Mundi Festival, the Anima School project and the Life Drawing and Animation Workshop. In the final considerations, conclusion is that the approach of animation through intuitive and spontaneous methods is shown to facilitate and motivate the awakening of a yet little know faculty of the human being: that of being able to reproduce and control time through virtual movements.
