link pixel color to light color

I'm looking to see if there is a way to link the color of a light to a pixel of an animation. (preferably an image series/ifl)

The easiest way to explain is to think of an LED wall. as the color of the video changes, each led/pixel changes with it.

I'd like to have 20-100 target lights each mapped to a different pixel of a single video.

I was originally trying to see if there was a way to wire parameters either by having an animated texture on an object and wireing to a color of a specific area but couldn't seem to figure it out.

I ran in to this post on the Area from quite a while ago that does something similar but the script doesn't work.

Is what I'm looking for feasible? possible?

Thank you
