Theo Jansen creates huge wind-powered sculptures.  His sculptures are very lightweight, pieced together using plastic pipes and cable ties.  He has such a perfect understanding of movement that they appear incredibly life-like.  He sets them off across beaches and they will happily walk for miles.

Animators also need this understanding of movement and anatomy.  They may be tasked with animating something that at first glance does not look human or believable.  They need to apply their skills to keep the object acting and reacting in a realistic way.  That is key to having an audience not question the authenticity of a character.
