With a few features added and a few removed, the code is almost complete. Some hardware prototypes are too! Like the front panels and the back led panel. over 500 ws2812b-202s FTW!

Anyway, with the code mostly complete (just a bit of refactoring and cleanup) and all the features fleshed out, it's time to work on the rest of the hardware design. Gotta get the layouts right. Also gotta figure out the power supplies. That's probably the last big challenge.

Added a pick of one of the display modes.

So a shot list of the features completed
