This is the Little Blue Something in the Black Brilliance case from Nocrotec and NixieKitWorld.com . This clock is sold as a kit and this particular one features Burroughs B-5853 tubes with blue LED under lighting but other tubes and under lighting options are available as well. (You can see other variations of the same design here.)
The Burroughs tubes used in this device are some of my favorite. They are not nearly as large as an IN-18 but they are very legible with crisp edges around the numbers and a proper numeral 5. The tubes feature a fine mesh which is almost invisible from a few feet away and the envelope is flat at the top except for where the gas was evacuated. I’m not sure what the point is of forming such a nice top (as opposed to a rounded version) but does add a nice visual effect to the device.
The enclosure is a shiny black acrylic with four flat metal bolts on each corner. It is assembled in the same way that other Nocrotec enclosures are with each side fitting in to grooves in the base to form the shape. With that said, there are no lose pieces and the enclosure feels sturdy. It is not a kid’s toy, but it still feels solid.
The LED under lighting is the same blue led setup that Dieter uses for many of his projects. This contrasts nicely with the orange glow of the neon digits but the color is user selectable (at the time of assembly) and the green led lighting options appears quite nice as well.
The LBS setup actually has a few different options for maintaining an accurate count of the time. It supports DCF inputs (for users within Europe) and GPS (via a DCF converter). Both of these options are extra and do not ship with the device. The board can also accept a 1PPS input if you want to sync it to another source. Lastly, the device measures the line frequency and automatically compensates the crystal to ensure long-term stability.
The board supports a few different methods for prolonging the tube life. The user can set display brightness via the switches on the back and he can set auto off times via a jumper when assembling the clock. The board also supports an LDR which allows the device to automatically dim in proportion to the ambient light in the room. This has the advantage of being automatic and significantly increases the life of the tubes
Recently, Pete launched his new Nixie QTC format for mid sized tubes. Let's take a look at what he's got:
To begin, QTC stands for "quick tube change." The QTC design is an interesting clock kit with the ability to easily replace tubes that previously were hard wired (such as an IN-8-2, Z5070M, or ZM1210). He does this by putting them on a mini PCB with a connector on the back so the tubes can easily be swapped out. Nixie tubes do eventually wear out and this is an elegant way to replace them. One of the advantages of having all of the tubes on mini PCBs is that the main board can support multiple types of tubes with no configuration.
The nixies are drive in a multiplexed display mode. The tubes are driven in a 3x2 multiplex and generate little noise and no perceivable flicker.
This device also supports GPS synchronization making it one of the most affordable clocks with this option.
The following features are standard for the kit version:

"Lars" and "Laura" are two old school Nixie Clocks from NixieKits.eu. At the time of writing, Laura is no more, but "Lars" (the little clock on top of the larger one) is still available. NixieKits.eu seems to have lost the drive to make new clocks, or even replenish stocks of the old ones, and it appears that as the old models run out of stock they are not re-ordered.
In any case, "Lars" is still available, and has 6 x IN-17 tubes. This video shows some of the display effects in action.
The display effects are the same as the ones that Pete Virica uses in his QTC clocks. The PIC micro controller software was designed by him and modified Jürgen for these clocks. The lack of updates to this firmware might be a sign that nothing new is coming out of this collaboration.

Here is a new clock coming soon from NixieKits.eu - this is Laura:
An IN-2 clock, based on the features from Sven - incl. Alarm, but with some more improvements:
LEDs on rear for: Alarm, DST active, Time Sync, Time Data input
The PCBs are made with a lot of tiny SMT parts, but they are all pre-assembled and soldered. So building the clock within 2 hrs. is not a problem at all.
