As people said before, it's all eyecandy, nothing useful.

Also, if you're making a flash website that's meant to strech to the browser's size, MAKE SURE ALL THE GRAPHICS IN THE .SWF FILE ARE IN VECTOR FORM. It looks really ugly when you have raster-style graphics streched out to some ambigous form like 313.37%. If you really want to make your website look great, aim for simplicity. If it works for Google, then why not you?
