Made this as an instructional piece for a newbie. It turned out to be priceless in many ways ... watch the eye as the draggable moves ...
Sorry, but I can't see anything different in this. The movement of eyes seem to be completely natural. I have seen that before, a lot of times. Can you please explain me what you were trying to show, if you don't mind?
Oops... I didn't see the title, so what I understood was correct. You wanted to show how B's eye tracks a free draggable. Cool...
