Bob Dullam holds a place of high regard after his work on a full scale, working Tumbler replica from the movies Batman Begins and The Dark Knight. Constructed in his two-car garage with little more than pictures and the extra features from the DVD.
And here's one made out of Legos.
Tumbler model based on the batmobile from 'Batman Begins', made entirely from Legos. Has working steering and suspension. See www.minipix.co.uk for more details.
