Yes, doing this with javascript sounds like the right way to go.
(As I understand it, the animation would then be carried out on
the client side -- that is, by the browser executing the javascript.)

Thanks for sketching out some of the details. I will experiment
with this approach some time in the future.
I did implement a solution where I scheduled a sequence of
WTimer::singelShot calls spaced a few hundred milliseconds
apart that update the text so as to add one character at a time.
But it does seem "heavyweight" to orchestrate this animation on
the server, rather than pushing the processing to the browser.
