Web design / flash / video idea

The idea came to me while watching a video on a facebook page - the notion of a dynamic video on a static, white page was interesting. Looks a little like a window - especially when its not centered or the focus of a page (i.e. a youtube video page). Like this, but with the video showing motion its more interesting (and without the buttons around the video):

The idea is outlined here in my notebook, but its the notion of a page that looks like a straightforward webpage with an embedded video - but something happens in the video that breaks out into the page. A flood, a fire that catchs onto the type and spread across it, a person that gets out of the video and climbs up the navigation bar. I'd like to play with this idea, maybe get something up on my website. as an example.
