You have seen propeller clocks before, but what about a Nixie Propeller Clock? I didn’t think so! Check out the link for code and a schematic.

“I stuffed the board with the PIC, the crystal oscillator, two logic chips, 10 HV transistors, the nixie, the HV inverter from a disposable camera flash circuit, the 7805 5V regulator, a 0.6 Farad memory cap, diodes, and the pushbuttons for setting the time. Rather than taking apart the motor to obtain power from the armature for the spinning board, I ripped apart another cheap motor and pulled out the armature and brush contacts and put it on the outside shaft of the other motor. The shaft was long enough for the armature and the cylinder that holds the spinning board.”
