Red Eyed Robots

I was wondering why is it we commonly associate red eyes with evil. I guess it's from some biblical verse explaining demons in some physical detail. Was it always this way in literature? Where did it start?

I wonder if it was ever attempted on stage?
Anyway, early movies with AI and robots, like Metropolis didn't mainstream the trend.

It seems it wasn't until the heyday of 1980-1990's Hollywood that it was widely adapted and almost seems common.

Automated Camermen 2

The machines would be able to self organize via GPS and modify configuration.
Here the system has been adapted as a rail for the camera to follow while recording.

Autonomous Cameramen Continued

If the robot recognizes the position of each camera actuation and compiles that data with the video (which would be aided by currently existing RealD 3D technique) you could produce a much more stable and information-rich model of what you're filming.

This would be an advantage for next-generation holographic display.
Multiple units such as these could act in synchronization in capturing a scene for 3D use.

The green and blue regions (x and y axis actuations) outline where the AI system would receive the position information from. Also note the Segway/PUMA design, for maximum stability.
