[themes] Theme menu system

[Roger]

Our page will be 2 parts.
Animage header with regularly changing quotes and a wheel menu instead 
of a rectangular menu.

Menu system will be a wheel with 12 spokes.
Each gap between the spokes has an image.
On mouseover the image will enlarge somewhat and when the gap between 
spokes is clicked a new page is opened.

We can do this in javascript and html  but I don't know how to call the 
javascript and make it go to the appropriate page with Drupal 7
I think I need to reference the correct node in the javascript but am 
stuck on how it should work.

Thanks
Roger
