I have been using VMD to make movies of chemical reactions for a
presentation, and it has been very useful. Now, I would like to place a
title at the top of the movie, where the text displayed depends on the
frame. For example, I would like the label to say, "Before Transition
State" or "After Transition State" depending on the frame number. I
already know how to use the GUI to place bond length and angle labels, but
it seems that these labels can't be used to write a title.

I think that I need to know two things:
1) How do I display arbitrary text in an arbitrary location?
2) How do I change the displayed text based on frame number?

Thanks for the great software,
