LinkSfx JS
This JavaScript adds a special effect to your links when clicked.
The original "a" html tag does not need to be changed.
This script uses special effects library from Scriptaculous JS.
Here we have Link A, click on it to try it out.
Here we have Link B, which opens a new window.
Links like this which have a "rel" attribute are not modified, so scripts like LightBox should still work.
Have a look at the source code of this page to see how easy it is to implement.

Tested and works on Firefox 2.0.0.3 and Internet Explorer 7.0.600.16386
