This is my clock.  I am the proud owner of the last one made according to the creator himself.  The display in this clock is a Russian Nixie tube called an IN-18 / ИН-18.  This is a really odd display.  There are 10 filaments inside of the tube.  Each one is shaped in the form of a number.  The tube is then filled with neon gas and a little bit of mercury to prevent cathode poisoning.    When ~180vdc is applied to one of the numbers, it glows.

Six of the IN-18 / ИН-18 tubes are used to display the time.  Like the Scope Clock, the time is set via GPS but a built in clock keeps the clock going when a signal cannot be located.  The tubes are some of the largest that were produced in quantity which adds a collector value to the clock.  Since they do wear out, I have a second set stored in a hard Pelican case.

This clock is based on Vacuum Fluorescent Display tubes.  They are a seven-segment based display like most led clocks but these are quite a bit different.  For starters, this clock costs nearly 100x as much as your normal department store clock.  The digits have a beautiful cyan color and the design of the tube allows you to see the inner workings.  Image and brief description are from Nocrotec
