I love watching interesting, non-traditional forms of animation, and Marcus and Hannes Knutsson's recreation of Super Mario Bros. -- using nothing but beads and a lot of still camera shots --  certainly fits that bill. I cannot possibly imagine how many hours of work went into this project, but considering how great the final product looks, I believe this to be time well spent.

Also, I found myself laughing at the clever way Mario takes out Bowser. Be sure to watch the whole video.
