Though the classic brick has not changed since it was patented in 1958, the Lego brand has evolved greatly in the past half-century.
The simple building toy has grown into an empire boasting enormous playsets, board games, video games and even an awesome movie (with a sequel on the way).
With sets related to Star Wars, Harry Potter, Batman, The Avengers and more, Lego has basically had your childhood locked down for decades.
