Clock "Lichtzeitpegel" (like Duesseldorf Fersehturm)

This is a clock that shows the time like the "Lichtzeitpegel" on the Duesseldorf Rhinetower.
https://de.wikipedia.org/wiki/Lichtzeitpegel

The time is shown by a WS2812b LED-stripe wich is powered by a arduino nano with a little RTC-shield (TinyRTC).
The parts can easily be sticked together. No glueing neccesary.
