I have seen this mentioned here before and agree that it looks very cool. the only drawback that I can see is under the "terms of use" near the bottom of the page. Sci-fi3d wants the user to not only give credit, but to actually do so using text on the image itself. I seldom use other artist's stuff 'cause I'm a modeler and I usually like to "roll my own", but if I do use something by another artist I am always careful to give credit where credit is due. Sci-fi3d's terms would have you putting a de facto "watermark" on your image in order to satisfy their terms of use; something that I am not willing to do.
