This is Smaug, from The Hobbit behind the scenes. Just click the flag at least twice, and watch. sorry about the bad animation quality. Smaug is a dragon, and it is very hard to dress up exactly like him. So, people designed Smaug, and the dots and sensors on the actor sense which way he is moving, and makes Smaug do the same movements on a computer screen that is not in this animation. The actors used the same method when they played Gollum.
30 second animation if it helps, my profile picture is Smaug.
