I don't know of any sparkling text, but there are web
sights (like www.mrexcel.com/archive/Formatting/644.html)
which can show you how to make you text flash from
regular to, say, bold-red. Do a web search on
"excel flashing text".
(unless its really necessary, why not keep it simple, and
just use a noticeable font, size, color, and style??)
