Modal Window on mouseOver?

Modal Window on mouseOver?

Good morning,

I was wondering - Is it possible to display a modal window (Preferably one which can display HTML and not just images) when a user hovers over a link, as opposed to a mouse click?

What I would essentially like to do is create a "menu" button/link which when hovered over would bring up a full page modal window with clickable content inside of it.

I've been browsing the 'net for a solution/example but the only one i've found so far is made in Flash. For an example of what i'm trying to achieve, take a look at http://www.journey-to-zero.com/ (Flash based site)

Thank you.
