The nature of nixie tubes makes any clock made of them relatively indistinguishable from its brethren, short of the composition of the base. There's not a lot of variation: six nixies lined up in a row, fluorescently glowing strangely sinewy numerals in the dark. But I still love the look for a bedside clock. This one is $350: it's like a Cold War nuclear countdown to the 6am apocalypse of waking up.
IN14 Brushed Clock [Tubeclock via Uncrate]
I used a Nixie tube calculator in university. It was a basic four function twelve digit model about the size of a small bar fridge!
I just did some shopping and figured I could build from scratch a clone of this clock for less than $100. I need a clock in my living room, and this would be sufficiently geeky, and fun to make too!

nixie tubes are lovely things, the tubes themselves are starting to become expensive to acquire.
