Whenever this question is asked, the answer is always "Please, do not do it"

Here is part of a reply from J.E McGimpsey some time ago:
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.

I wouldn't recommend that you use blinking text. It is rather
annoying. However, if you want to do it, you need to use VBA code and
a timer. See http://www.cpearson.com/Excel/BlinkingText.aspx for
example code.

Note the caveats Chip points out about blinking text being annoying.

Users will soon learn to disable macros.
