Hmm. I saw an interesting display device at a friend's the other day,
in some sort of Genrad whatsit that he was getting ready to scrap.
(He's keeping the display digits though.) Each digit is a box with a
bunch of tiny incandescent bulbs mounted in the back; each bulb
illuminates one layer of plastic at the front; these layers are
stacked and each has a digit (or other symbol, e.g. decimal point)
etched in it (as a bunch of etched dots). There's a diagram on the
side of each digit-box that indicates which bulb illuminates which
digit or symbol.
Anybody got any ideas about this thing? His speculation is that
somebody didn't want to pay for nixies (but he's amazed at what these
things must have cost to build in comparison), mine is that they
wanted something nicer than a column of digits 0-9 with a bulb behind
each.
