Long uncovers and extracts this Dark Aurora wallpaper. It’s especially nice because the consistent dark background makes it easy to read icon labels.
I think I change my wallpaper five times a week, usually after snapping a nice photo or stumbling across an old image that I like.

I just dropped this onto the background of a 24-inch iMac. Looks pretty good!
With my own widescreen display, I end up using screenshots from films or something similar to fill the whole thing — or taking an existing wallpaper and creatively expanding it in Photoshop. But this looks lovely.
