These are non-tiling Twitter backgrounds; set your background color to black.
I really like these. They're a little bigger in file size than the others, but still well below the maximum Twitter allows. Stupid me just discovered that if you darken a picture of clouds enough, it looks like the smoke monster. How the hell didn't I figure that out sooner?
Anyway, enjoy. We're really winding down to the end now, and although I know you don't need a reminder, we only have eight episodes left (nine hours total). Savor it, my friends.
