If you're looking to add animations to your website without writing any code, I highly recommend checking out jQuery Transit for smooth animations. While you can use CSS3 animations or transitions for simple effects, jQuery can help synchronize events and make your animations more dynamic. Another useful plugin to consider is jSound for adding multimedia elements to your site.
There are plenty of other plugins available for adding animations and sounds to your website, or you can even create your own custom code to incorporate HTML5 audio elements for hover effects.
