Google UI Fade In

I just notized, that www.google.de shows only the logo and the search box. The remaining UI, containing other links, like pictures and video search etc., fades in when you move the mouse over the page.

Its a very nice effect. Because, the moment you see the page, youre eye is catches by the Logo, then moving to the search box. But the very moment you realized what you want to do (search for something ofcourse) all the other links fading in, catching youre attention, promoting the advanced features.
