We will present movie clips, showing the evolution of the milli-arcsecond structure and magnetic field of 12 well known blazars. The images are based on six epochs of VLBA observations at 15 GHz spanning all of 1996. Intermediate frames were constructed by linear interpolation using AIPS. The movies show clear superluminal motion, and also the complexity of the magnetic field evolution in these sources.
