What I needed was a tactic that can get the users attention when they receive a new message while the browser is minimized. I couldn't find a way for the icon on the task bar to blink but I found an alternative that still fills the need. @HariKrishnan gave a link that led to a couple of googling that made me discover Web Notifications. You can find a very simple tutorial here.
Cheers!
For future reference I added the tut here since its just a two step process . .
Step 1
Ask user to allow webkitNotifications (Same thing with the html5 geolocation)
function askPermission(){
webkitNotifications.requestPermission(testNotification);
}
Step 2
Creating a notification
function testNotification(){
var notification = webkitNotifications.createNotification('IMAGE','TITLE','BODY');
notification.show();
}
(Note: Multiple notifications will stack)
