I'm trying to write an application for a small business checkout counter.
I'm trying to find a way to make the characters in a cell blink when an
erroneous value is input. This would bwe a lot more visible to a cashier
than a simple color change.

It could also be something to add to the formatting pop-ups in excel to
accompany Bold, Italic and Underline.

Does anyone have any ideas or suggestions?
