creating a page that displays continuously changing data

Is there a way for a page to self update (without the user having to press the refresh button) when the collection it gets data from has changed?

I would like to have a page of my site displayed on a monitor. The data will be constantly changing and I dont want someone to have to refresh the page everytime as there could be multiple monitors showing the page at the same time.
