Last I checked, in Rick and Morty, there is 1 P3-ROC, 2 PD-16s, 4 SW-16s, and 5 PD-LEDs. The reason it gets expensive is that I insisted on using a crap ton of direct drive RGB LEDs. This requires extra PD-LED boards. If I would have been able to get serial LEDs working reliably enough under a playfield, I could have gotten away with 1 PD-LED.
