Halftone Navigation: queue

Halftone Navigation: queue

I want to create something similar to flash with halftone navigation script . you can see the script here...

http://tutorialzine.com/2010/01/halftone-navigation-menu-jquery-css/

I want to queue two shapes in this script. i.e. If I hover Home I get one shape that shape goes away and other shape appear.

I want it to make like flash Intro so that function runs with just load event with two three shapes queued up.

MY Try:

I tried the normal way putting
draw('house');
draw('wrench');

But it didn't worked out.
