I'm not a tube guy normally (solid state forever!) but I do enjoy glow tubes (partially evacuated tubes that glow from plasma when turned on). I found an interesting project, "Build a Vacuum Tube Nightlight (http://www.grandideastudio.com/vacuum-tube-night-light/ http://www.grandideastudio.com/vacuum-tube-night-light/ and https://worldradiohistory.com/hd2/IDX-Consumer/Archive-Poptronics-IDX/IDX/90s/95/PE-1995-03-OCR-Page-0003.pdf https://worldradiohistory.com/hd2/IDX-Consumer/Archive-Poptr...). It's a simple circuit to drive the tube from wall power, and an enclosure to keep the tube safe. I learned that you can just buy nixie power supplies and adjust them to the strike voltage of the tube, which is a bit nicer than the custom circuit I linked. but be careful- you're either dealing with mains voltages or high DC voltage, both of which can be pretty painful if you make a mistake.
