I've attached 2 pictures I made in photoshop. With "Control room" (below) I just thought I'd put together 3 frames of the movie to give you a bigger picture of the room and a better idea of the orbiting planet and ring.

With "Blueprints" (below) I was hoping to get some ideas about what this map is of, perhaps the building
you're in or the starsystem. If it is infact the starsystem, then you'll notice that the yellow
ring would probably be the halo but it cuts through a big red ball/planet, and if you look at the
Controlroom pic, the only thing the ring cuts through is that purple thing at the top, so it could
either be a planet or the room's ceiling..
