In html-speak this is called a marquee and is very straightforward to do, including having several options with links. You just need an html codeblock and an iframe.
First put the following codeblock on your page:
[!--
[[code type="html"]]
<HTML>
<BODY>
<marquee
behavior="alternate"
direction="left"
bgcolor="#D5F8B4"
scrollamount="6"
onmouseover="this.stop()"
onmouseout="this.start()"

<a href="http://strathviewconsultants.wikidot.com">Strathview Consultants</a>
</marquee>
</BODY>
</HTML>
[[/code]]
--]
Then underneath it add an iframe to reference that codeblock:
[[iframe http://yoursite.wikidot.com/yourpage/code/1 frameborder="0" scrolling="no" width="600px" height="50px"]]
This gives the result below. I have put an explanation of the different marquee parameters on my page here.
Edit: curiously Gareth I have an aunt and uncle who live in Bishops Cleeve.
