These are serial numbers #001 and #002 of a limited edition of binary clocks. They feature an exposed printed circuit board and a heavy wooden base. The clock has a high precision quartz oscillator and a back-up battery. The time is shown in 24-hour (European) format in BCD on 13 green 3mm LEDs.
Young electronics engineers seem to be fascinated by LED shows including Christmass trees.

The problem I see with these young electronics engineers is that they use PICs and AVRs for driving their LED shows where a simple logic circuit would suffice.
