Adding Easing to this Script.

Adding Easing to this Script.

Hi, if you visit the following website: http://driz.co.uk/

You will see that I have a link in the top left corner that uses Jquery to make a grid appear. I have the following files: jquery, jquery.grid, and jquery.easing.

What I'm wanting to do is add the Bounce effect that the easing plugin has to my grid instead of it just sliding down and up. I've had a play but just end up breaking it :/

Here is the code for jquery.grid hopefully some one can see an easy way to add in the easing that I desire thanks.
