The Luminous Electronic Bargraph Nixie Tube Clock
Sorry, make that The Luminous Electronic Bargraph Nixie Tube Clock, Timer, and Sound Level Meter. Nuvitron has built their repurposed Soviet-era Nixie tubes into a piece of retro-futuristic desktop art that can do it all. You don't even have to say "Alexa" or "OK Google" to get it to hop to.
Toggle The Luminous Electronic Bargraph Clock between its 3 modes to see the time of day in hours on the top minutes on the bottom, a visual display of audio levels in your immediate surroundings, or a countdown from 1, 5 or 10 minutes. During the latter, the Nixie tubes also exhibit, according to Nuvitron, "a pleasing, and quite hypnotic, pendulum effect." To change modes, simply turn the clock 90 degrees and built-in sensors will detect its position and activate the appropriate setting. To turn it off completely, lay it on its side opposite the clock mode.
