Less random cat pictures, more pumpkins!
It's Serenity, from Joss Whedon's Firefly. Which you should watch. Seriously, go watch it now. As for the pattern, I picked it up from someone who posted it on the Zombie Pumpkins forum, by the name of vivid_figment. I'm not sure if they're the creator or what, they only have one post. But they have an awesome pattern! It likely wasn't intended to be shaded, but I think it looks cooler this way.
