The ANIMAL algorithm animation tool. In this paper, we present Animal, a new tool for developing animations to be used in lectures. Animal offers a small but powerful set of graphical operators. Animations are generated using a visual editor, by scripting or via API calls. All animations can be edited visually. Animal supports source and pseudo code inclusion and highlighting as well as precise user-defined delays between actions. The paper evaluates the functionality of Animal in comparison to other animation tools.
