Nixies came in many sizes. In truth the ones this guy is making are about the biggest I ever saw. I still own several old HP frequency counters and even a few meters with nixie displays. Prior to cheap LEDs they were about the only option for numeric displays besides edge lit lucite. (Which I also possess an example of.)
One of the interesting things about the video is that the process is almost identical to production of vacuum tubes (save adding the nobel gas and not adding a control grid.)
Nowadays even LED displays are vanishing in favor of LCDs.
You don't even have to believe in the gods to know when they are pissed off at you.....
