I have found in my years engrossed within the LEGO building community that builders utilizing the “Chibi” style of design are few and far between.  Kevin Ryhal has created a set of Chibi 501st ARF Troopers and AT-RT walkers from Star Wars: The Clone Wars.  His attention to detail mixed with his “Chibi-ness” design is amazing, but add in “mecha” style articulation to the joints and it becomes most impressive.
