animation_test, an Octave code which illustrates how to create an animation.
To my surprise and disgust, the only option that I could get to work involved creating a sequence of PNG files, and then using a system() call to the imagemagick convert() function to create a GIF file. There are other, much better animation file formats, but between the limitations of Octave, convert() and ubuntu, this is the best (and worst) I could do.
