When does life “spark” in a face?


How “human” does a face have to be before it looks alive to you? Try this demo to test your intuitions.

Click "MORPH" to start the animation. As soon as the face looks like it has a mind (that it can think, feel pain, make plans), click "IT'S ALIVE!" to see just how human it needed to be.
