You get the idea. Since most Nixie tubes can only display numbers, they'd be mounted upside down so you could use calculator spelling (e.g., 07734 translates to hello, 5318008 translates to well, you get the idea, again).-- ytk, Jun 05 2015 Nixie tube http://en.wikipedia.org/wiki/Nixie_tubeFor those who don't know what [ytk] is talking about. [Vernon, Jun 05 2015] Thanks for the explanation, Vernon. But blah on the idea. Not in a good mood, so just blah.-- blissmiss, Jun 05 2015 So you'd communicate in leetspeak and volapuk?-- normzone, Jun 05 2015 The word "Nixie" is actually an Americanised spelling of "Nixi", the Latin equivalent of "Andrew", after the inventor's son.-- MaxwellBuchanan, Jun 05 2015 Or, communicate by finding signage with the words you want, and driving over it such that it becomes entangled in your rear bumper.-- sninctown, Jun 05 2015 random, halfbakery
