There is a new shaving commercial where heads turn into cubes at some point and the parts of the face still move. I assume this done by image warping and texture mapping, bu there might be a non-digital mechanism too. (Digital and non-digital get harder to distinguish as techniques improve.)

Yes, I worked on this ad. The warping is all done digitally. First, we scanned in the faces from orthogonal points of view, and mapped them onto the cuboid heads. Then we warped the images of the cuboid head toward the shape of the real head, and warped the real head back toward the cuboid head, then cross-dissolved between them. We call the technique "morph" and it is similar to the technique that ILM uses for some of their work, but better (IMHO). This commercial was done at PDI, where I used to work. thad
