Thanks Skip, Rather than create your suggestions in a complete animation, I have animated just one of the examples as you suggested. You can see it here: http://www.youtube.com/watch?v=rj4IW2r7s3s
Let me know if this is what you had in mind. I added the extra horizontal arrow, since without it my bias to reading left to right caused the end result to be counterintuitive. I think I still prefer the previous option of having the Plus (+) appear in place over the argument, as the design is simpler and much more amenable to matrix and vector examples; but before I scale out to the full video of your ideas, let me know if I am on the right track.
