I arranged this Photoshop Challenge on CSF back in 2006, so I guess it’s about time i get it uploaded to the page: Everybody had the same spaceship setup on a blue screen, and everybody did a great job!
Check out how I made the setup and what people made of it (in Miscellaneous>scenes).

Are any of you readers interested in having another go?
I consider creating a sequence of three setups with dogfighting among large container carriers: If you keep the style consistent (but vary the backgrounds), they could be linked into a comic-strip-type action sequence.
