overLIB is a JavaScript library created to enhance websites with small popup information boxes (tooltips) to help visitors around your website. It will provide the user with information about what will happen before they click on a link as well as navigational help. Not to mention that it looks cool.

Here is a sample of how it works:

Haven’t seen overLIB in action? Take a look at these small examples. A plain popup, or perhaps one with a caption. You can also make them stick when you click, plus, you can place any html you wish in them. There is lots more you can do like placing them on the other side of the mouse, snapping to a grid, fixating the position (you might need to scroll up to see it), having background images and lots lots more.
