Hi there

I'm curios to know if there are jQuery alternatives to the java scripts used by amazon.com Those things are difficult to implement, but I'm interested about them built with jQuery.

I'm talking especially about the following scripts
- the menu from the left: http://ww.amazon.com
- the drop down menu, when you cross over the top orange button from page http://www.amazon.com/gp/site-directory/ref=topnav_sad
- the scrips which change the product picture http://www.amazon.com/Canon-PowerSho...dp/B003ZSHNGS/
