The main issue I have is that I am working with undergraduate students
who have no experience installing things from scratch.  In this
context I am stuck with whatever is in EPD.  Currently EPD is at
1.0.1, which does not have animation.  Will this file "just work" with
1.0.1 or 0.99.3?  I don't have any aversion to using animation.py, I
just need to be able to use it within a stock recent EPD.

Cheers,

Brian
