For several years now webcams have shipped with special face-tracking features that can give a user access to a number of virtual disguises. False mustaches, round glasses, even the ears of cats have been donned by giggling teens across the internet, but software engineers Kyle McDonald and Arturo Castro have taken the technology further with celebrity masks, allowing themselves to take on the appearance of Brad Pitt, Marilyn Monroe, and Michael Jackson. As you can see in the video below, the effect isn't perfect, but it's close enough to be creepy in the way one set of facial features can "stick" to another's. 

The trick is performed using a combination of face-scanning and face-tracking software and while Hollywood masters have performed these tricks in the movies already, McDonald and Castro's version is impressive because it takes place in real-time and without the benifit of having access to the celebrities themselves. There's a big difference between using special cameras to scan a person's face for the animated 3D detail needed and simply grabbing it from available YouTube footage. It'll be interesting to see how this might surface later as a commercial product. Would you pay for the use of a celebrity mask? Would it disturb you if it were easy for someone else to assume your face?
