Every window manager has a different look, and themes help personalize that look.
Being a blackbox and Tolkien fan, I found a way of combining two of my favourite things. All these themes work fine on 1024x768 resolution and are suitable for blackbox 0.51.x and up. The actual pictures vary in size themselves, but I've limited the full-size pictures below to 1024x768. Make a directory called Tolkien under your personal blackbox directory in your home directory. All the wallpapers use the xv program for the rootCommand , but you can use your favourite program.
