LEDodecahedron

We're going for it now, 612 LEDs, 51 of them controlled by a single IS31FL3733 chip

Bunch of IS31FL3733 on a pentagon PCB controlling a bunch (76? - 106? - 128? - 181?) of RGB LEDs. It's 51. Was hard enough to route anyways!

since the IS31FL3733 is not recommended for new designs, why not redesign the LED PCBs with the IS31FL3741. gotta research that - would mean more LEDs (117 instead of 64).

According to my table, I would get 2 more rows around the cube with 106 LEDs. 

There's only one ADDR pin here, so you can have a maximum of 4 panel adresses, but definitely managable to address half a cube with the RP2040 that has two I2C channels.
