Mark Constable has created an excellent, and well-documented, resource for some interesting advanced jQuery Examples.
The examples range from the simple (such as fading text in and out) to the complex (such as live searching or input field focusing). All of the examples are fully documented, which makes this a great place to learn some new techniques from.
Also, Mark provides a simple format for submitting new examples, so I imagine that this repository will only grow in size (it’s already up to 10 entries). So check it out and be sure to thank Mark for all his hard work!
