You've found a little personal project!
This is a nixie tubes clock I built from scratch. I sold a few on Trademe.
The tubes are original Russian nixie tubes - all the digits are individual filaments inside a vacuum. The electronics is based on Arduino. The base is stainless sheet, laser-cut, folded, TIG welded, and polished to a mirror finish.
This clock is still lighting up my bedroom.
Well... all of it.
