Random thought re. a'banner

This may be a totally impractical waste of space but: I just thought that it might be cool to have a 'dynamic', albeit a slow one, to have a world time zone clock graphic as a banner. Ya' know, one that shows a basic sense of countries and where sunlight happens to be passing around the world at any given time. Sort of a nod to 'one world, one people'. Am I making sense? Maybe?
