In Xfce I change a panel icon depending on a condition with the script below. I created an icon for my script and then I created the alternate version by hand and the script swaps them. this updates right away. Not flashing but maybe you can use an animated gif for icons, not sure...

#!/bin/sh

test=`grep -l 111.72.252.91 /etc/hosts`
if [ "$test" == "/etc/hosts" ];then
	# Ad blocking seems to be on right now:
	rm /home/doug/Desktop/Adblock\ On.desktop
	cp -a /home/doug/bin/Adblock\ Off.desktop /home/doug/Desktop
	echo -n "" > /etc/hosts
	cp /etc/hosts.normal /etc/hosts
else
	# Ad blocking seems to be off right now:
	rm /home/doug/Desktop/Adblock\ Off.desktop
	cp -a /home/doug/bin/Adblock\ On.desktop /home/doug/Desktop
	echo -n "" > /etc/hosts
	cp /etc/hosts.normal /etc/hosts
	cat /etc/hosts.adblocking >> /etc/hosts
fi
