I know Chimera46 uses these spots for his renders http://www.renderosity.com/viewed.ez?galleryid=934523&Start=37&Artist=chimera46&ByArtist=Yes but I think is his own work, he is a trek fan too, we did a star trek project toghether a while back: http://www.renderosity.com/viewed.ez?galleryid=1025145&Start=13&Artist=chimera46&ByArtist=Yes he made the renders and the story, I just cropped it and panneled it. Maybe if you ask him nicely he may let you use it. :-)
