Nixie tubes and font, based on IN-14 tubes from the former Soviet Union. Nixie tubes are popular within the maker community for clocks and other retro-art, steam punk and vintage tech projects. A nixie-illuminated Stein's Gate was featured in Disney's recent Tomorrowland movie. The numbered font set includes the flipped 2 digit that was used as a 5 by some manufacturers. The digits are layered in the same order as the actual tubes.
