Here is a really nice robot with eyes that actually allow you to see where he is looking! Quite good, I definitely would put that sort of thing in a robot.

Quite a few people find this robot scary, by the way. Would it be the same as with how a robot looks: appreciation rises if it more human until it suddenly falls when it becomes too human?

Besides the eyes, there is also some facial expression even if it is only through opening and closing of the eyes.
