I've a 'tube.inc' and 'tube_000.pov' (a 'nixie tube' implementation), posted
apparently by user "Thomas", the datestamps say 'May 19th 2020' (though likely
to be date the copy was created); cannot remember whether downloaded from here
or found elsewhere on the net, and searches so far w/out result.  can post a zip
(on the understanding not my code/no (copy)right/etc)
