Okay, I see the confusion—no you wouldn’t: reverse what you’re seeing. What you’re seeing in the trailer the camera’s point of view—those close ups of Donald Rumsfeld talking. Imagine for a second that’s what your robot was seeing through its camera-eyes, as for Mr. Rumsfeld he was seeing a projection of Errol Morris’ face OVER the camera lens. This technique is called Interrotron. What I’m proposing is instead of projecting an interviewer’s face on a beam-splitter in front of the lens—you project your glowing anger lights. A similar technique is used on almost all news broadcasts with text instead of video. As you can see from the trailer, there’s no ghosting or second face over Donald Rumsfeld’s. Which would mean your red light wouldn’t have any bleed into the robot’s vision but be visible to anyone looking at the robot.

Ah. Now that you mention tele-prompters, things make more sense. Thanks!
