I got tired of the bright colors of my Tesla Model S background hurting my eyes, so I made this Art Deco’ish desktop background from scratch just now. It’s 1920 x 1200, but you can easily use GIMP to scale it to any size. I highly recommend the “Sinc (Lanczos 3)” scaling filter in GIMP for this application. Please let me know if you get any use out of the image. The second picture is a screenshot of it on my Windows 7 box.
