From Bricks to Bothans Forum (dedicated to LEGO Star Wars) is having a Steam-Wars Contest, where fans get to submit their LEGO creations of Star Wars vehicle done in steampunk style.
The contest will run until January 31st and no entries have been posted yet (so it's a thread to watch). This one above, by Brickshelf user Jerrec is a fantastic steampunk X-Wing fighter!
