indicated by lighting them from below with a red or blue LED. I've got
the special effects visualized, but that's the really easy part.
Would not a green & red Ne-2 would fit the mood better.
If you have the HV why not go nixe tube?
Given 4-bit binary, how many more tubes do you think it'd take to do the
1-of-10 decoding?
