Meet the Mosquito Turbulenzzzo Nixie Clock: a desktop nixie tube clock with 4 x IN-12 tubes that can display time, date, and temperature. It has multiple backlight modes. You can set it to just show the time or additional information.
This clock is powered by a 12V DC adapter. Copper Cat Art Group are the artists behind this handmade nixie clock. The bad news? Something like this doesn’t come cheap.
