> Implemented the minute pause of the Swiss railway clocks
The station clocks in Switzerland are synchronised by receiving an electrical impulse from a central master clock at each full minute, advancing the minute hand by one minute. The second hand is driven by an electrical motor independent of the master clock. It takes only about 58.5 seconds to circle the face; then the hand pauses briefly at the top of the clock. It starts a new rotation as soon as it receives the next minute impulse from the master clock.

want to make clock -> need browser...
i do not want to live on this planet anymore
I would have done this in either Processing, or if it was connecting to something running Plan9 I’d do raw draw commands.
but it's a pre-bought circular screen, raspberry pi and a browser... i could use it to ask google the time, the clock is just a formality.
thinking about it a little harder, i guess the focus is not really the project and more so the watch faces.
