It’s just some javascript to show an initially hidden div.
I have seen an example at "Prototype window’ http://prototype- window.xilinus.com/samples.html .
Clever, because there are a bunch of stuff it handles (resizes,
moving etc…)
I have been looking in to doing this for the past couple of weeks. I
have used many javascript libraries to do this. All have been
successful, but with varying degrees of complexity. Some merge well with
rails, others seem to purposely clash ;). Google around for Prototype
Window Class, Lightbox Gone Wild, and the rails plugin RedBox.
