If you are (or going to be) web designer / web application developer, I would like to recommend you to learn up jQuery - it will help you to make an impressive web site.

How do I found it?
Recently, one of my customer would like to have her website with list of photos which capable for horizontal scrolling. Initially, her designer gave us the design with capability of scrolling. However, it is some kind of ActiveX plug-in which IE will prompt for installing. hmm.... I feel that it is not that prefect and it will drop the "image" of my customer web site. Therefore, I decided to googled for a better one. I found jQuery through the sorgalla.com which the site has a lot of samples "Riding carousels" which fulfill my customer's needs. All the samples are plugin for jQuery!

Okie. That's all about history of finding it. So what is jQuery? It is free and open source software. Google, Dell, Digg, Mozilla.org etc are also using this plugin.

jQuery is a new kind of JavaScript Library.

jQuery is a fast and concise JavaScript library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery is designed to change the way that you write JavaScript.

I won't say much how useful of it, you may find more from the tutorials. It provides the tutorials in different languages.

Lastly, I shared with you the riding carousels feature I have implemented on my customer site - Bloomwear.com :)
