Is there a hack to add a fourth ring for Moon Phases. This could be pointed up around a back lighted Shadow Box with 16ish phase cutouts. Any thoughts or code?

No one has done this so far, but there are places in the charlieplexed matrix that you could fit a few more LEDs in. Take a look at the circuit diagram and read up on charlieplexing, if you aren't familiar with it.
