Flash Embeded Image Gallery

I need someone to code up a conceptual image gallery. It will need to be created in AS2. The gallery will work like a map and will show 16 items in a grid (4x4), when a user clicks on an item the effect will be the screen will zooms to the item and the item fills the screen. When a user clicks on the item again it reverse back out to the full grid. Each item in the grid will be its own movie clip and will not be xml driven but rather stored in the library. I have attached a .swf of what it should look like.
