I haven't seen much yet on folks creating their own cards and/or custom ships. In Wings of War (now Wings of Glory) it became fairly common to create aircraft that hadn't yet been released for the game.

Has anyone started tinkering with Photoshop yet?

Over on afewmaneuvers.com, GeckoTH has rolled up a whole slew of custom templates for just about everything in the game. I think they're all in this thread:

Have fun!

And boardgamegeek forums under x-wing variants forum has a bunch of custom cards.

Yeah, I think Gecko's templates are on there too.
