@jasoncoon @wizard I spent some time on performance and code cleanup, and now my version of ColorWave is ready for the world. Share and enjoy!
It looks like uploading to the PixelBlaze pattern repository is broken, so I posted it as a gist.

Full disclosure, I used LLMs to help write this. See next post.

@jasoncoon @wizard Garrr... 🧵 3/N was supposed to be a video. Let me try again...

@jasoncoon @wizard This video shows the palette transitions better.

I've been writing some new shaders for it too. This is a continuation of @jasoncoon and @wizard 's Color Palette Waves. I added continuous progressive palette changes and true black pixels.
It has 33 color palettes, and it plays them in random order. So there are 33 × 32 = 1056 different palette transitions.

I made a simple stand for my Fibonacci. I have ideas for a more elaborate stand, but this one works.

Today I finally assembled the Fibonacci 256 Expanding HDR that I got from Evil Genius Labs nearly two months ago.
The colors are really vivid and a lot easier to photograph than my LED cube.

@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.)

Today's 🐇🕳️
Anyone interested in dynamic #LEDLights will likely find this a fascinating read.
I now have ideas! I'm gonna have to make time to dig out a #PixelBlaze and Fibonacci display and do some tinkering. 😃

My final assembly table is full of parts for #LuxLavalier, #EvilGeniusLabs Krakens, Fibonacci64 Flowers, Fibonacci256, and Fibonacci512!
Have you ever seen so many #PixelBlaze in one photo?! 🤩
Or PixelBlaze Sensor Expanders still panelized?
Lux Lavalier is in stock in @wizard's store:

Everything else is coming to my @tindie store in the next few weeks!
