Perhaps Links Would Work
As I mentioned in a previous post I wrote about a question on how to get people to hover their mouse pointer over parts of a page to trigger a script to run. I have no idea why it was a question at all.
Links seem to be pretty obvious as a way to attract a mouse pointer. All you need to do is make whatever you want people to point at, look like a link or clickable image. That would be relatively easy with JQuery. You could even use it as an actual link if the user has javascript turned off in their browser.
