Dinner-dinner-dinner-dinner BATMAN! I never tire of that song. I doubt it features in Warner Bros’ new iPhone application though, which is based on the recent movie blockbuster The Dark Knight.

The app is called The Dark Knight: HaHaHa, and is a nifty personalisation application that lets you take a photo, slap some Joker artwork onto it, and then send it to a friend. Nothing more, nothing less.

Warner Bros has just released an update to the app though, which improves its positioning, scaling and rotation system, making it easier to use. It’s free, naturally, being a promotional app. You can get it from the link below.
