I found this old nixie controller board at a flea market, bought some 8421 tubes on eBay, and added a second board with timekeeping logic (AVR microcontroller and DS1307 real-time clock) to drive it.
It's in my office at work and runs on a programmed schedule; the display automatically turns off at night to conserve the tubes, and doesn't turn on at all on weekends.
More details are at http://www.msarnoff.org/projects/nixieclock2
Great, now I need to replace my flat LED Matrixes (is this how it's said? Matrixes?) with those gorgeous tubes :(
By the way, awesome job there (:
