Box with posts

Hi to all,

what i need is a little complicated. Check this web site out.

I’m looking for a plugin that allows me to do a thing similar to the video box on the website linked above. I need to put in the little boxes on the side some posts’ titles and then to obtain a preview of them in the big box on the left.

OR, I need to find something like that. So basically, little titles of posts and then, on mouseover or clicking them, the big post preview.

Thank You!
