Animation is essentially the art of movement, and movement in the animation becomes a powerful tool for transmitting messages. 2D animation involves forming movable frames in two-dimensional space. To achieve effective visual communication it is necessary to respect the natural laws of motion and the laws of motion in 2D animation, which were established through the first animated films, but also the laws of spatial composition established during the centuries of art history. Usage of time is also crucial in animation, and it is measured in frames per second. Space and time are unified through sequential composition, where you can use forms of continuity and forms of discontinuity. Animation has its own technical constrains, which largely depend on its purpose: video, television, film, Internet or CD-ROM. These technical constrains can be restrictive, so it is sometimes necessary to compromise in formatting, using effects, or quality so the end-user can browse animation without any disturbance. Animation designed for multimedia has its special requirements arising from its interactivity. In order for the end-user to be satisfied it is necessary to thoroughly plan every step of production, to take into account all constraints, and perform necessary testing. Animation has its own particular process of making which consists of the preparatory phase, the conceptualization of ideas and the performance itself. Finally, each element of the animation has its birth, life and death, and a story has its beginning and end, although it does not need to be told in that particular order. Animation allows the manipulation of space and time and in animation there is no limit to the imagination.
