This was a short 2-hour fun project.

I wrote a small execution module for Salt that takes a text string and a mode ("status", "warning", "error") as input and uses the Sense Hat's Python API to display the text on the Sense Hat's 8x8 RGB LED matrix display.

The mode is translated into traffic light colours (green/orange/red)

The API can do more than that, like displaying single letters or numbers rather than the rolling text, using the LEDs to display an 8x8 picture/icon, showing progress bars etc., so the project should be easy to extend.
