"Welcome" Announcement flash

I have downloaded the plugin Welcome Announcement and would like the plugin to run before the home page in order to get the same smooth opening as the latest Apple website where they start with the new McBook Air. I think Welcome Announcement can do the trick, but as it is now the plugin starts first after the page it self. the other thing is that the menu bar is visible the whole time. I was thinking that if I could start the plugin first and then fade into the home page it would look like the latest Apple solution. Does anyone know if this would be possible?
