I made this background for whatever it is you want, whether for a blog or twitter or even a desktop
It is square so you can use it to tile to fit any screen.
I tested it on my twitter, i have a wide screen, and it looked great tiled, so hopefully it will look good on your screen as well
Just click on the thumbnail to see it full size, then right click and save
Hope you like it as much as i do *wink wink*
