Map Blinking

I constantly get requests to add the ability to blink counties on the map. I ran some experiments today and had success in blinking a color. The only problem was that it blinked that color no matter where it appeared.

It took 17 milliseconds on my 3.4 ghz pentium 4. While it is computing the image, nothing else can happen. That does not seem to bad, but for users with slower machines it could be a problem.
