Tonight, I got two things done. The first I named “vectored calls,” where I can have the clock display a completely different face based on the mode selected with a rotary encoder. The second is that now it displays latin numbers around the clock hands instead of just dots. See the pictures below.
Note that I was able to take the pictures in quick succession because the vectored calls let me select the different display modes just by turning the knob (yes, I retook the last one a half-hour later).
