Custom Jscript for website interactive menu

I would like a custom script which will act as a menu system on my website which is an image in the centre of the screen, with 4 or 5 links (icon & text) arranged around the edge of it. When clicked, the selected icon needs to move into the centre of the screen, and the surrounding links need to fade out and either be replaced by up to 5 others OR load an actual page. This needs to be customisable, since I will need to edit it here. I have a relatively good knowledge of HTML, so can easily update links and images. I don't want to use Flash for this.
