David: I Believe in Harvey Dent Too
Okay, The Dark Knight, which is the next entry in the revamped Batman franchise, has some internet marketing going on already.
www.ibelieveinharveydent.com is a fake barebones campaign website for Gotham D.A. Harvey Dent (who later becomes Two Face).
There's another site
www.ibelieveinharveydenttoo.com which originally contained the same content, but had an animation of clown makeup being drawn on Harvey's face, and then dissolved to a photo of Heath Ledger as The Joker. However, as you can see if you follow the link, the site has changed. If you take a look at your scroll bar, you'll see that the page extends way down. If you highlight all the text you'll see "ha ha ha ha ha" repeated all the way to the bottom.
But is that all that is there? No. There are single letters within the rest that spell out "see you in December".
I have found the above information across several websites. What I'm about to tell you, I haven't seen on any others.
You see, I'm somewhat of an amateur cryptologist, and I'm pretty sure that there is much more here. The varying size of the "ha"s can't be random, especially since a look at the style sheet shows that each is set up as its own style class. Interestingly enough, there are 36 seperate classes; one for each letter and digit.
Unfortunately, this is as far as I can go with this today, as I'll be busy until 10pm tonight. Anybody else care to crack the code?
