"jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development."

That's the blurb from the website and if all makes sense to you, then you probably don't need us, but if you don't know your Ajax from your elbow then let us introduce ourselves. jQuery is a rather wonderful javascript library that allows developers (like us) to make really interesting stuff happen on your website without the need for plugins. It'll work cross-browser and it'll work on an iPad or iPhone (unlike Flash).

Need some examples? The project image galleries on this very site work via jQuery. The portfolio shuffle? jQuery. The blog? You get the idea.
