Ian made an awesome Nixie tube ornament –
“The Nixie Tube Ornament is a homage to the light-up&motion ornaments from the early 90’s. The ornament looks cool on a tree and makes a great gift. Finally, a use for IN-12/15 top view tubes!
I used an IN-15A symbol nixie in this ornament. An IN-12 works great too.” – Link.
