Text Animator
Description: Text Animator is a great cross-browser text effect. It fades in and out infinite text messages, with each message optionally being clickable. The only shortcoming of this script is that it has to be absolutely positioned on your page, meaning you have to manually set the coordinates of exactly where you wish the animator to appear on the page. A small sacrifice to make in return for such a cool effect...

Directions 
Simply copy the below code and paste it anywhere in open space (not contained inside any tags, such as <table>, etc).
As mentioned, since the script uses absolute positioning (as opposed to relative-absolute positioning). you need to manually set the coordinates of the animation. Scroll down to the bottom of the script, and change the top and left attributes to the desired numbers. For a list of FAQs about the script, click here.
