I was thinking of taking my animated texture and making it very transparent, and fuzzy and place it bigger on the ceiling, like it's being projected there, very faintly.
Oh, please don't. The "projected image on people's faces" thing is one of those movie cliches that I hate, because it doesn't happen in real life. It's anti-realistic, not super-realistic. (I always flip the movie screen a rude gesture when it happens. :)
Sure, linking panels aren't real life, but what are they *like?* Like a TV screen? A TV screen doesn't project an image on your face -- just a diffuse blueish glow. Like a window? A window doesn't project an image on your face either. (Unless it's a pinhole-sized window!)
If you want to go this route, I'd love a diffuse *but featureless* glow on the ceiling, with the same general color tone as the panel image. To be really sexy, have it brighten and dim just a little bit, matching the passage of bright and dark features in the animated panel.
