What would be involved in making a label flash?

we've discussed this before, actually:

that example sets up a short number of flashes. if you want it to flash slowly until the user acknowledges somehow, set the timeout to a slower value (half a second, one second, etc), and store the timeout tag so you can remove the timeout externally when you know the user has responded.

I'd have to do something like create a new thread that wakes up every so often and alternates the colour of the label, right?
Suggestions? ie is this more hassle than it's worth? Are there any decent alternatives?

yes, nine times out of ten threads are more trouble than they are worth, and cause more problems than they solve. for this type of problem, the appropriate solution is to use the event loop and timeouts.
