Before you proceed check out the following link... (As posted by JE McGimpse
some time back)

US Government sites are prohibited by law from displaying flashing text
(between 2 and 55 Hz) due to triggering seizures in those with
photosensitive epilepsy.

Many other organizations try to conform to section 508.

Hi,

A personal view; which i suspect is supported by many, is that if I was
presented with a worksheet with flashing cells I'd close it and delete it but
if you must then have a look here but note the warnings.

For work in progress etc. I'd like to be able to fill a cell in excel say
yellow but have it flashing so attention is drawn to it. Excel 2002 if
possible.
