Dear Will,

The camera
movement I would like to do is a little more than simple rotations or
spirals, so it would be very helpful to me to be able to rotate about
an arbitrary vector, rather than just the principle axes, in mdo
commands. Is there a way to do this?
There is. The movie.py script does exactly this: camera movements.
Basically, any movement can be achieved by adding x,y and z rotations.
You can specify how quick each axis is to be rotated and so on. Any
camera movement can be smoothed, if You like.

As You wrote You are making movies of trajectories i assume that Your
animation uses more than one state. Movie.py doesn't get alongt with
them at the moment. This is because i don't know what would be useful.
If You want to go with movie.py, write me, and we'll get something on that.
