Actionscript 3.0 :: Making Movieclip Randomly Move Around A Constrained Area

I have an array of display objects that are simple scattered circles on the stage. My goal is to have them move around randomly within, say, a 5/10 pixel radius/range from their original x and y. Sort of like fireflies, but not as jittery and fast, I'm looking for something real smooth. What I have now is something like this:

Code: Select allfor (var g=0; g < total_circles; g++)
{
circle = new DrawCircle( 3, 0xFFFFFF );
circle.x = random; circle.y = random;
addChild(circle);
jitter = JitterCircle( circle, 10 );
}

So as you can see for each circle I call a class JitterCircle and pass it two values: the actual display object and the range I want my circle to fly around in.
Inside JitterCircle I have this:
