Nice navigation script

Hi there…

At the site of the week votes from last week i saw this website…

http://www.chromazone-imaging.co.uk

i know the invinite menu tutorial here at kirupa… i know it’s a bit like that. but just the moving movieclip

do i need something like

my_mc._width = Stage.width + 100;

and

my_mc._height = Stage.height+ 100

I think that’s to easy

does anyone know a tutorial how to build this sort of navigation? or someone who can give me any code to start?

Thanks
