How to animate a string to track a moving CSS element?

UPDATE - I asked for help correcting my first attempt using the animate SVG plugin, which now has a solution (follow this link) that answers this question effectively. Although attr (), as Jleagle pointed out, could also lead to a solution

I animated an array of css elements using jQuery, and the next step is to track each element with a graphic line . One end of the line should remain stationary, and one with the element.

I thought I could accomplish this with SVG and the corresponding jQuery SVG plugin, but I ran into a lot of problems I was wondering if I should just approach it from a different direction.

Below is the code for animated boxes with three lines of SVG so you can see what I get. There is also a JS site script

Javascript

$(function() {
var balloons = [$("#box1"), $("#box2"), $("#box3")];

var lines = [$("#line1"), $("#line2"), $("#line3")];

function act(jqObj, speed, change) {

    jqObj.animate({
        'left' : change
    }, speed).animate({
        'left' : -change
    }, speed, function() {
        act(jqObj, speed, change);
    });

};
for( i = 0; i < balloons.length; i++) {
    var speed = 2000 + Math.random() * 501;
    var change = 10 + Math.random() * 26;

    act(balloons[i], speed, change);
}
});

HTML / CSS

<head>
    <title>Proof of Concept Page</title>
    <style type="text/css">
        .html .body {
            position: absolute;
        }

        .box {
            position: absolute;
            width: 100px;
            height: 100px;
            position: absolute;
            background-color: red;
        }
        #box1 {
            margin-left: 300px;
            margin-top: 60px
        }
        #box2 {
            margin-left: 500px;
            margin-top: 20px
        }
        #box3 {
            margin-left: 700px;
            margin-top: 50px
        }
    </style>
    <script type="text/javascript" src="jquery.js"></script>

You can put text and elements in the same tag and put text in text.
Then you do not need to capture the animation of two objects.
Hope all is well.
