This sites moving navigation effect is done via scriptaculous and
would much prefer to use a jquery plugin instead.  Does anyone know of
a similiar plugin that would allow for horizontal movement as well as
vertical and allow me to customize the speed and "easing"???
Anyone suggestions would be much appreciated!
