This script adds a rich HTML tooltip to elements that's revealed when the mouse rolls over them, in which the tooltip follows the cursor around as it moves about within the element. The tooltip can be "stickied", or kept visible on the screen by right clicking on pressing "s" should the user wish to interact with some content within the tooltip, such as click a link inside it. The contents for each tooltip are simply defined as regular HTML on the page, making them very easy to define and customize. Throw in a subtle fade in effect, and you've got yourself a tooltip that can do more than just show extra information, but serve it as well!
