One of our Facebook followers submitted this clock. It is a Z660M based clock in a handsome black walnut case. The aluminum bezels are custom machined for this clock. Check out his site and build log for more info. He has a few videos of the clock in action as well as photos of the internal workings. (Incidentally, he also makes a nice Arduino Nixie Shield that's worth checking out.)
Tim Walker sent me a link to his great Scope/CRT clock build. The internal mechanism is based off Thiem-Work kit. He used a DG 7-16 display and the enclosure is made out of a clear plexiglass. One other feature that he included that I haven't seen before is the inclusion of a motion sensor that only displays the time when motion is detected. That has to be one of the most elegant burn-in protection mechanisms I've seen.
Lastly, be sure to check out his neon work at http://timwalker.cc/. He has a lot of cool stuff to show off.

Muris Trax contacted me the other day and wanted to share his single digit in-8 clock. I've been meaning to add a user-added content section so here it is! (Images and video used with permission.)

Timekeeping and measuring
Inside of this box there is a 3V Lithium battery (CR2032) that keeps the PIC microcontroller running even when the clock is turned off (the wall adapter). This is very convenient because after powering it up again, we don't need to set the time - again. If a button is pressed during a power-down, nothing will happen. With PIC microcontroller I used a "watch" crystal at 32,768kHz. It's value is pretty cool and now we will see why. PIC16F84 has internal TMR0 counter that increments itself no matter what the PIC is doing at the moment. Think of it as a threaded sub-program. This counter can generate an interrupt when it's value overflows from 255->0. We can also prescale this counter to slow it down a bit so we can make it generate an interrupt on every 2, 4, 8, 16, 32, 64, 128 or 256 overflows. So, when we finally connect our 32,768kHz crystal on PIC microcontroller, we should also know that the speed it runs at is divided by 4 and this characteristic is only found with PIC microcontrollers. This all means that our PIC runs at 8,192kHz which tells us that TMR0 will overflow 32 times per second. Now when we prescale it by 32 it means that it will overflow once per second and generate us an interrupt. This we can use as a very precise time measurement. Anyway, source code is available for download so you can poke around.

The TubeClockDB / Tube Clock Database is a collection of nixie clocks, vfd clocks, vacuum fluorescent clocks, crt clocks, scope clocks and oscilloscope clocks. I have fully assembled clocks ready to purchase, kits, or even individual nixie tubes. If there is something that you think would make this a better resource, please contact me!
