Pitch-class clock
Every chord as a shape. Octaves fold away, so every C sits at twelve o'clock. Moving a chord to another root turns its shape, and swapping major for minor flips it over.

Each chord you play lands here, with how it got there from the one before.
Clock
Notes sit at their exact pitch, so in an unequal temperament they land a little off the marks. With a 19- or 31-note temperament on the minichord, the clock follows it.
