Using the new Intel RealSense 3D camera developers kit, I used the facial recognition APIs as the basis for this project.  This project was for my Extended Media II course.  This project was an experiment of the psychology of mirrors and emotion contagion.  When a participant looked into the mirror the bottom camera would recognize their emotion and play a corresponding piano riff, thus encouraging participants to try making different facial expressions.  The camera on the top of the mirror was live streaming what the mirror was seeing onto the wall behind the person looking in the mirror.
