I keep expecting Lucas to attempt to animate the panels like these in the OT, when I heard that the DVDs had been altered beyond the 1997 versions it was the sort of thing I expected to see (I'm not sure if I'm disappointed or relieved).
If someone was to try it, it would be a lot of hard work and it could go very wrong if over done.
I'm assuming it's a repesentation of the situation in space (which might not change very quickly) perhaps adding a few slow moving elements could convey the Imperials getting into position and coming into range.
But it would be a major hassle during the shots of the set battle damaged, surely the screens would go blank after smashing?
