The Magic Mirror is just a little demo. It’s still not complete. The idea is to add Facebook-Connect so it would know what kind of [spoiler-alert “product”] to show, personalized on your gender, age and so on..
I’m also not sure if there is a company that would want to make fun of their clients (Dove is just used as an example). So this might just remain a little lab demo.
Note: If you can’t see yourself in the mirror after confirming in the camera settings, just right-click and pick the right webcam driver.
