Lennykravitz.com => how to make this effect?

Hi all,

does anyone know how to make this effect??
i have allready seen it one on a tutorial, but didn’t understand it completely…

when you click an option from the menu,
that ‘it’ zooms out, and then zooms in on the wright one

are these all swf-files, or just different movie clips??

and how to make it??

thx very much
