      We describe various forms of algorithm animation which have been
      studied, presentation techniques and programming environments
      developed for this purpose in recent years.  We present a
      description of the environment {\em AnimA}, which we designed and
      implemented with the goal of aiding in the process of production
      of algorithm animation providing users with facilities for the
      production of animations of any algorithm in a systematic way, by
      means of congregating in a single environment tools for animation
      support such as: uniform graphical interface, preprocessing
      system, automatic maintenance of libraries, reusability of shared
      libraries and dynamic linking.
