Programming has started and I've made some test sequences to get a feeling for the final look. It's kind of hard to capture the real impression because of the high contrast but here is a short video, showing:
- flashing through LEDs at startup
- bottom line doing some kind of loading animation (e.g. when connecting to wifi later)
- quickly counting through minutes and then hours for demonstration
- finally showing current year and month+day
Brightness sensor is working as well. I also have some ideas for making the appearance more diversified with different animation patterns and maybe an option for randomly toggling optional features, e.g. 12/24-hour modes.
Next thing will be setting up WiFi to get current time automatically and maybe also to be able to connect with a smarthpone for configuration... should be possible...
