In the wide panorama of 3D reconstruction of models taken from photos or movies, one stands out in particular:  "Total Moving Face Reconstruction"
 
Researchers at the University of Washington have developed a system that takes a person's face from a series of photos of reference present in a single video, and reconstructs a 3D shape with high detail for each frame. Really interesting.
