Banner solution with a LINK to the new site
Well, it can't be both ;)
There's a whole continuum:
--image showing URL that the user has to type in
--plain-text URL that user has to copy-and-paste into address bar (assuming user is one of the two people left on earth who understands what an address bar is)
