What about a drawing growing spline that follows the path of a human head? Neat and simple. Again the appeareance of the infinte floor, a dancing spline generating the context. A couple of macro cameras showing the behaviours, a lot of editing going on. See how with a small 3d rendered animation you can stretch a piece by making various camera renders, a bit of post and a well pre pro script. A good way out for those without a 16 core processor machine.
