I was asked how to make a scrolling ticker in the style of CNN testerday. If you've tried it's not simple to get a neat result especially with very long messages. Charlotte was at the next desk and says "How can it be hard - it's simple in html, just put the html into the slide"
mmmm, actually that's not so simple either .....
Here is the result of me giving it some thought. No guarantee it's experimental but try it and let me know. I'd like to hear if you can improve it too
