I was inspired by this after seeing the Dyson Sphere Episode for TNG (the name escapes me at the moment), but some of the theoretical ideas authors are coming up with today could be kinda cool to implement into ST:O for exploration missions or as part of episodes
There's actually something in game that reminds me of a Jupiter sphere that i've dubbed the 'terrasphere'. It was in Cardassian patrol mission that i've actually only just discovered on my alt. Terrasphere
If they retextured the sphere they could easily make a dyson sphere or Jupiter sphere.
