Here's a webm showing a thing I made with termite and bspwm:

I made my bspwm configuration revolve around a single 'theme' file that determines many settings, such as window gap, border width, what terminal and vim colorscheme to use, what fonts to use, and what icons and items to use in the panel. After that I made a script to symlink a named theme file out of the appropriate directory and reload wm configuration. Termite is an interesting terminal because if it receives the USR1 signal, it reloads its configuration, allowing for pretty smooth transition between themes, as opposed to urxvt. One thing missing to this that I'm not sure is possible is the ability to send open vim instances the command to load the new colorscheme. I know it's possible with gvim + remote, but trying to evade going outside terminal. Still looking into it.
