I did a project like this for Burning Man, making Really Large "Nixie"
tubes using 2-liter soda-pop bottles with the labels removed. and
large-diameter (5mm) orange EL-wire for the digits. To drive them, I used
a little AT89C2051 microcontroller for each digit, driving a bunch of
MAC97A6
I've been thinking of making some Numitron type large displays with LED
filaments, but this looks interesting as well. Driving the large number of
filaments is going to be a pain in the butt though, and shame about the
relatively short lifespan...
