Flash scrolling gallery - up down right left

Question

I found a Flash parallax scrolling gallery tutorial here:
http://www.webdesignerwall.com/tutorials/parallax-gallery/
but I want the mouse move up and down as well instead of being just right to left.
could anyone help me plzzzzz?
I believe it has something to do with "Z" as well az "X" and "Y"
To be more specific I want to be able to build something like this
http://www.ff0000.com/
when it comes to navigation, simply to be able to move the screen
according to viewer's mouse, up, down, right and left
Here is the code:
stageWidth = Stage.width;
speed1 = 15;
speed2 = 14;
mc1Width = front_mc._width;
mc2Width = back_mc._width;
mc1X = front_mc._x;
mc2X = back_mc._x;
lock_scroll = false;
_root.onEnterFrame = function () {
     if (!lock_scroll)
          scroll_mc();
function scroll_mc() {
     var xdist = _xmouse-(stageWidth/2);
     mc1X += -xdist/speed1;
     mc2X += -xdist/speed2;
     if (mc1X>=0) {
          mc1X = 0;
     if (mc1X<=stageWidth-mc1Width) {
          mc1X = stageWidth-mc1Width;
     if (mc2X>=0) {
          mc2X = 0;
     if (mc2X<=stageWidth-mc2Width) {
          mc2X = stageWidth-mc2Width;
     setProperty("front_mc", _x, mc1X);
     setProperty("back_mc", _x, mc2X);
//create an empty mc container for content to display
createEmptyMovieClip("content_box", 200);
content_box._x = 195;
content_box._y = 92;

Thanks "dmennenoh"
what I'm looking for is a simple and complete tutorial of how to create a
home page in flash
which is sensetive to visitor's mouse so that later on I would be able to
use it as a template and load any kind of swf files into it.
I guess my biggest problem is the explanation of what exactly I want!!!
