In one of the scenes in the second part of the Weeping Angel episode there's an eye.
Just after the Doctor has finished yelling at Amy (who still can't see) he looks at River and speaks to her. She's standing in front of a screen (small one bright blue) and on it is an eye searching around for something.
When was the last time the eye was visible? The crack in the wall. The eye searching for Prisoner Zero.
Yup. There is. It's only there for a couple of seconds though. While Amy is running through the forest.
