Cheers
Great Science Fictions (not especially 'sci-fi' / space westerns !) shows lot of objects(Fictionous or 'reals' - in theory) who can interesting Celestia add-ons. There are, some times ago the Larry Niven's Ringworld (by Mark Griffith), the Clarke/Sheffield's Spacelift (by Thomas Guilpain) made for Celestia (are they avaible, again?)...
But some of other are meriting a look: "Plan?te de Roche" (Rocheworld, showed by Robert Forward) for example, or, of course!, Dyson sphere !('Orbitsville' series by Bob Shaw -Ireland- [Jack?

] or 'Omale' series by Laurent Genefort -France, and other authors -Iain M Banks in the great 'Culture' series?)
The Dyson sphere, (like the Rinworld), is an artifact made with the planetary system materials (planets etc.), but in this case it encloses completely the sun in a sphere: the lifely surface, clouds, etc. are, of course
inside!(same problem to model it as the -other SF images- hollow Earths...)
Hope to see model of this.. other than, if in the future I will be able to model something, i try this First: i *love* this artifact.
