@jasoncoon recently posted a cube shader that runs colorwaves around the cube's perimeter. I tried expanding that to three nesting cubes.

This color scheme is a throwaway, but I tried a spatial dither to smooth the hue changes at low brightness. There are interesting possibilities to explore there.

@jasoncoon I have sad news. My LED cube's power supply died. It supplies 2-3V now, and the ESP32 reboots constantly.

I have great news! I hooked it up to a bench supply and it runs fine. With all 512 LEDs at 100% white, I measured 13.08A. So I'm ordering a new 15A power brick from the piranha retailer now.

@jasoncoon I'm finally getting into writing shaders for my PixelBlaze/Evil Genius Labs LED cube. I call this one Bubble Phi. It uses the R₂ low discrepancy sequence to pick the colors, thanks to @mbr for showing it to me. (I've used R₁ color sequences in other projects.)

@jasoncoon I made my LED cube match my avatar!

Stupid LED tricks...
