cool free javacript tool

This is not a product plug, just something I came across:If you're familiar with javascript, there is some free code called jQuery (http://jquery.com/) that allows you to create different effects that mimic Flash. It looks like a good bit of javascript knowledge is needed, and there still might be a learning curve (books have been published on jQuery). Anyway, Check out these demos of what all this can do. http://www.webdesignerwall.com/tutorials/jquery-tutorials-fo r-designers/I don't know how well this would work with Lectora, but since it just calls an external javascript file I don't see why it wouldn't work.
