I'm sitting here think about the ability to create a movie of plots, say
to watch the activity in some multidimensional data evolve. PDF files
work fairly well at this if one just keeps hitting return fairly fast.
But creating some output format that could be stepped through with a
viewer or movie player might be a long-term neat capability. Is that
what you have in mind with "animate"?
