Reface [Portrait Sequencer] (images above and video below) by Golan Levin and Zachary Lieberman is an interactive installation which cuts up and recombines users faces:

Reface uses face-tracking techniques to allow automatic alignment and segmentation of its participants’ faces. As a result, visitors to the project can move around freely in front of the display without worrying about lining up their face for the system’s camera. The video clips recorded by the project are “edited” by the participants’ own eye blinks. Blinking also triggers the display to advance to the next set of face combinations.
