Lo puoi fare tranquillamente con un javascript...
ti consigio quello che gentilmente fornisce html.it, e di cui ti riporto la parte dello script, che naturalmente puoi modificare a tuo piacimento:
Codice:
<script type="text/javascript">
//configure the below five variables to change the style of the scroller
var scrollerdelay='3000' //delay between msg scrolls. 3000=3 seconds.
var scrollerwidth='150px'
var scrollerheight='105px'
var scrollerbgcolor='#c6c6c6'
//set below to '' if you don't wish to use a background image
var scrollerbackground=''
//configure the below variable to change the contents of the scroller
var messages=new Array()
messages[0]="<font face='Arial'><a href='http://www.html.it'>Visita HTML.it</a></font>"
messages[1]="<font face='Arial'><a href='http://freephp.html.it'>Un sito pieno di script in php</a></font>"
messages[2]="<font face='Arial'><a href='http://www.forum.html.it'>Il forum di HTML.it</a></font>"
