This is a background that I made with mainly Inkscape, but a bit of Paint.NET. Feel free to use this background with credit! ;D This isn't just a picture background that you can use, it moves and tilts a bit with the sine block. :D Copy the custom block and the main script for your background. (The custom block is needed for it to work.) I recommend that if you use this as a background, then you should keep it interactive with the mouse pointer. ;)
