This guy challenged himself to make a wristwatch using 1968 vintage Nixie Tubes as the display. And he succeeded. It is truly a work of art. He sold it for $500.
Ooh... eat your heart out, Sir Clive Sinclair!
Brings back happy memories too: When I was a kid, the guy who ran the local pet shop owned both a talking Mynah bird and a Black Watch. Absolutely the coolest, most amazing place in the world to hang aged 8 years; we musta had eyes like dinner plates when he showed 'em off. :)
