If you head out to, which is the mobile version of, you get an animated alert that slides down the screen and points to the icon on your iphone that you use to make the site an icon on your phone's home screen.

Very, very cool!

My question is, how are they doing this? I've looked at the source code when I'm viewing the page from my desktop and I'm not seeing anything obvious.

How are they pulling this off?
