jscript popout menu

Hi.
I am looking to see if you have a plugin or a theme that supports images that can then have fly-out or pop-out links off of the image...similar to this site, http://cascaderidgeptsa.org, if you click on School, you will see a menu that flies off to the right. This site is horrible from a design perspective, but I like the flyout menu from an image...so just wondering if you know of a plugin that I might be able to use to do something similar.....and/or what theme you have that might get close to such functionality....or other ideas.

Thanks,
Kris
