Stalker is a cool jQuery transition effect plugin - when scrolled past, it attaches specified element to the top of the screen. As you scroll past it becomes fixed, and when you scroll back beyond the element, it goes back to normal positioning. See demo.html for an example.
Usage:
jQuery("#stalker").stalker();https://github.com/luxx/jquery-stalker
