Regarding Agent tracking, there is a piece of code that generates the green on screen warnings. A number at the end counts down from 1800 to 200, in steps of 200. When it hits 200, the Source Agent may appear. Of course, the best way to show that is another matter entirely.
Code:
setInterval(function () {
var b = $('<div></div>')
b.css({
width: '30px',
position: 'fixed',
top: '0%',
textAlign:'center',
left: randit(0,98) + '%',
color: 'green',
});
b.html(rchar());
b.animate({top: '100%', opacity: 0}, randit(1500, 5000), function () {
$(this).remove();
});
bloobs.push(b);
$('body').append(b);
}, 200);
