It's like geek catnip in the week of The Dark Knight's release: Batman's "Tumbler" Batmobile from Batman Begins... as a Transformer. See the whole thing and find out where it came from under the jump.

The image is a fan creation, courtesy of "Jolin" and "JesterJJZ" of indie video production house Jester Pictures, mixing the movie-style Transformers with the Batman design - Dig the pointed ears, chest and belt emblems - to create the kind of thing we should expect to see if Michael Bay ever gets his hands on Batman in the near future...
