ROFL, quoted twice in one thread! I'm going to mark this down on my calendar.

Sorry Phil, I guess I was as clear as black plexi on that one.  I've long admired your space station/ecosystem as shown in this pic- http://www.renderosity.com/viewed.ez?galleryid=677206&Start=127&Artist=drawbridgep&ByArtist=Yes. I've never attempted the like, and I haven't seen many examples of this particular sub-genre ,other than Pakled's "Asteroid City". Someday I may even attempt such a project myself. then I can join the "exclusive club",lol.
