Ticker Tape/Theater Marquee Display?

I'd like to have a small routine that would scroll a text message across
the screen inside a window, like a theater marquee or the old Times Square
advertising displays or the stock markets quotes at the bottom of certain
television programs.

The crude solution I've come up with is:

s = "This is a test string that will be scrolled across the screen like a
stock market ticker tape." ;

w = 40; n = 1;
nb = NotebookCreate[];
While[n <=StringLength[s] - w, 
   (NotebookWrite[nb, StringTake[s, {n, n+w}], After];
    SelectionMove[nb, All, Cell];
    n = n + 1)]

Can anyone suggest anything more sophisticated?  Why does this version
scroll so slowly?   Anyone know of a dot matrix type font that would make
the output look more realistic? 

Email cc of replies to siegman at appreciated.
