Add Jquery Easing Effect To Logo?

I need to make a tagline of a logo move.

I tried this plugin:

http://wordpress.org/extend/plugins/the-welcomizer/

I can get it to move left to right, up or down, but I’d really like to add some “bounce” to it using some jquery easing. I’m just not sure how to do that with this plugin. There are boxes for adding your own effects, I just don’t know what to write!

The other alternative would be to figure out how to do it without the use of any plugin. I basically have 2 images as part of a logo, the bg of the logobg div class is the primary logo, and then I have another image & div id for the tagline.

Here is the code I have to work with:

$("#logobg").fadeIn(2500);
$("#logotagline").show("drop", { direction: "right" }, 400,function(){$(this).effect("bounce", {direction:"right", times:2, distance:50}, 400,function(){eval(fn);});});

I don’t know how to put that into my wordpress theme though – I tried editing the functions.js inclufded in my theme as well as my own scripts, but nothing happens! I did call the jquery easing plugin in my header, but I think I am missing something still.

Any suggestions on what I could try?

Any suggestions?
