As long as you're going to pay too much for retro technology, why stop at transistors & 7-segment LED's?... Go for his Nixie tube clock!

A guy selling kits to make a all-parts-exposed digital wall clock that uses *no ICs* and *no crystals*. You build it yourself, 1250 parts to solder onto a custom board. Too pricey for me, otherwise I'd love to put one together.
ICYW, I dug around the FAQ and he is cheating a bit: he's using the 60Hz of the AC as a timer source.
Hmm, since it plus into AC, does that mean touching some parts of the exposed circuits might give you a nice zap?
