spritesmods.com has build a interner speed indicator based on a Dekatron tube, the result is great.
As most electronic engineers and hobbyists do, I have a great respect for the earlier ways of controlling electrons, before it was found out that silicon could be used to miniaturize everything a thousandfold. It is amazing that things like a vacuum, a glow wire and a bunch of strange-looking metal bits can actually do useful stuff. The amazing-ness of it all gets even better if there are visuals involved: while vacuum tubes only have the faint glow of the heater, tubes filled with neon are more interesting because they can be used to display stuff. Nixie tubes are a prime example of those.
