From darkhorizons.com:

As we knew on Thursday, a viral marketing effort had begun for “The Dark Knight” with a website serving as a political ad for Aaron Eckharts character of Harvey Dent campaigning for Gotham District Attorney in the upcoming “Batman Begins” sequel.

Now, over the weekend, Joker cards were “found” spread all over a comic book store in Southern California with the words “Ha Ha Ha I Believe in Harvey Dent Too.” A few hours later, up went the website ibelieveinharveydenttoo.com which results in the same promo image seemingly defaced by the Joker.

Cute, but nothing of note really. An input box asked for users to submit their e-mail address, and those who did received a link with co-ordinates. Once entered, each co-ordinate removed a 1×1 pixel from an image – an image that seems to be Heath Ledgers new look as The Joker in the film.
