Yes, this was the way to do it, and after some thinking it's also the
obvious way. Thank you for the kind help and the code (which I used parts
of).

The movement is still a little bit jerky. I think I have an indexing
bug somewhere in my code, but it's a lot smoother than it was before.

Well, this must be one of the more perverse projects, as I do this
experiment in Python. Not the fastest thing in the world, but very nice to
work with.
