Gang, I know this isn't nixie related, but I thought I'd bring it to your attention as we're all clock enthusiasts...

I've built one already and as a Word Clock it's pretty sweet.

I think it's doable with a single chip. I have successfully charlieplexed a single chip clock with 144 LEDs and this clock only needs 128. The issue would be how many LEDs are to be lit at any one time, to ensure the refresh rate is flicker-free. I might have to have a go at this after a few other projects have seen daylight.
