A tech demo known as FaceSubsitute lets you wear someone else's face by mapping your face on the webcam.
The browser based app, built by Norwegian developer Audun Mathias Oygard uses WebGL and ClmTracker, a Javascript library built specifically for facial feature tracking.
The app includes celebrity faces, random stranger faces, cartoon masks and a different category called Abstract that intentionally distorts one's face, Tech Crunch reported.
However, the app has slight glitches which include dropping of jaw of the pseudo face after some time. At present, the app has 17 different faces to try from.
