Digging into the Python libraries provided (dot3k) I found a few "hidden" features of the board. "Hidden" in the sense the components of the board support/provide these capabilities, but the official samples don't demonstrate them.
The following Python scripts show off a few of these "hidden" features. I have tried to write these in the "style" of the official Pimoroni samples.
NOTE: these have been tested using the Display-o-Tron HAT, not the Display-o-Tron 3000!
