DHTML - JavaScript Headline Waver Code

DHTML - JavaScript Headline Waver Code
Astonishing, what you can achieve by combining DHTML and IE's multimedia power. This script creates a dynamic news board with a flash like wavy transition effect between the messages. Add as many messages as you like. Set each message to a link of its own. Cross-browser (Netscape users will see a simple clean new sticker without special effect, works not with NN6). Easy configuration of font, font size, font color, background color and so on.

Installation
