[Creating Plugin:WP-jcumulus]Inspired on WP-cumulus (jQuery)Problems enqueue js

Hi, first of all, sorry for my bad english.
At second, if this post shouldn’t be here, feel free to move it into the correct place.

Now:
I’m trying to make a version of WP-Cumulus without any use of Adobe Flash. With jQuery.
I discovered a plugin in the jQuery-web, called stringball that could be usefull.

First of all I’ve have a little problem with the process of loading scripts, I read on the docs that it could be simple as putting:

wp_enqueue_script( 'my_script', 'direction/stringball.js', array( 'jquery' ));

It’s suposed to work, but I have no results.
Any ideas?

As for the rest, I will put an option panel, for customizing the plugin.

Here you have the “beta version”:

As you sould see, the code is a bit “dirty”, I’m sure that it can be improved.

Thanks for all.
