Check out this inventive online display ad for Greenberg the Movie.
- Opening panel invites you to tweet directly into the ad (you'd need to click for details)
- Clicking the ad forces you to watch a preview of the movie. Apparently, it's about a neurotic guy with wandering thoughts.
- You get to add your own neurotic thoughts by entering your Twitter username/password and tweeting it. No matter what you write, it will be perfectly aligned with the movie idea.
If that weren't enough, there's a good chance that the content of your tweet--displayed to all of your followers, mind you--is about Greenberg the Movie.
That's great stuff.
