Does Earth (when viewed outside or inside ESD) spin or rotate?
If not, it should. Would be nice if it did, and new continents were visible from ESD.
For that matter, how about making Earth move lively? Maybe put some ships and shuttles orbiting Earth? Starfleet and Earth would certainly have ships orbiting the planet, shuttles going back and forth from Earth to ESD.
I think Earth needs a re-design. it is the heart of the Federation afterall, it just seems like it should be more active, more lively, more scenic.
Only very slowly though, so slowly that implementing moving stars would be pointless IMHO
They could exaggerate the effect slightly so it's noticeable. I think that would add a really nice bit of visual fluff to the Earth area. They'd have to implement it in 3 places for consistency though: Outside ESD, inside ESD, and not forgetting ESD's lounge. I've noticed that outside ESD, Earth has moving clouds now, and the odd shuttle flying around, but viewed from the lounge, Earth has no moving clouds
