Rails - Jul 2006 - Is there an example of using "Prototype Window Class'' with rails?

I feel like a bit of an idiot asking this but does anyone have an  
example of http://prototype-window.xilinus.com/index.html  being used  
in rails.  Should I try and feed it through page.call using rjh.   
Like this:
page.call (''win = new Window("window_id", {className:
"mac_os_x",
title: "Sample", width:200, height:150});win.getContent().innerHTML =
"<h1>Hello world
!!</h1>";win.setDestroyOnClose();win.showCenter();'')

I think I am missing something really obvious.
