In response to a forum member's request, I recently created this Flash navigation system for a site dedicated to soccer.

> If you download and 'play' it, you'll see that it has seven main menu categories [the little soccer ball buttons] that reveal a total of around 23 sub-menu choices, besides having some amount of audio effects, button animation and a built-in hard-coded slideshow.
> For those interested in such things, I've put some of the resources used online for downloading. These are the general and reusable resources like the soccer ball animation and the short audio loops used for the buttons' "on (rollOver)" and "on (press)" events. A 503Kb zipped file.
