You guys gotta see this : YouTube - Terex RH 400 TechnicBRICKs: Week TechVideo, 2009 #12 - One beast of hydraulic shovel I found this from random google searching, and my mind is still blown away. It is such an epic win in every way. This is not a transformer toy. It is strictly a lego model of the terex RH 400 . But this could make me sh_ bricks ! Even better, it functions electrically, the shovel and treds actually work !
