If you want to develop a complete background/different clock layout/etc for the Nixie's then post up all of your image files I can roll it into the latest SVN that has kind of a "themable" structure to it; then a user can access the Nixies by pressing "Day/Night/Nixie" button, just like we do with day/night mode right now; the way I've got the SVN version setup that would be very easy to do...
