I'm not sure of the rules here, but I really need a new wallpaper.

I'd like it to have darker colours, and some flowing lines, if possible.

If this isn't the way to request, please close this.

Some details are needed

What size? (Screen resolution; right click on the desktop and then on customize or personalize or something, then go to screen/desktop/settings... one of those tabs, and it will tell you the screen resolution.)

My resolution really sucks, it's 1024 x 768.
