While sorting through some old junk I found the boxes to a few of my favorite Game Boy Advance games, including a receipt from 22 years ago. 😆

Fibonacci256 Expanding HDR is now available!
I'm experimenting with different Voronoi grids behind the black LED acrylic diffuser. I think I prefer the one on the right, since it allows more light to bleed onto the surrounding wall.
Which do you prefer?

You probably shouldn't throw away your current revision V5 if you already have one, but if you want to breadboard some electronics jumperlessly and are really stoked on the integrated OLED thing, I have them up in my store (along with some cheaper refurbished units.)

What I find really neat about the pattern in the previous post is if you watch any pixel it just smoothly blinks off and on at the same rate the entire time. The further the pixel is from the center the faster it blinks. It's a similar "incremental drift" as a pendulum wave:

Instead of pixels being only off or on you can use a wave function for brightness. The period of the wave is each pixels' radius, you get a much smoother pattern. The #Pixelblaze code is short & relatively simple: gist.github.com/jasoncoon/db...

In disc phyllotaxis, like Fibonacci256, lighting every N LEDs from the center produces a pattern. If N is from the Fibonacci sequence a spiral (or mesh of spirals) is produced because the divergence (angle of succession in a single spiral arrangement) approaches the golden ratio.

Just before Christmas, I finally put up the amazing Fibbinocci spiral flower light sculpture that I got from @evilgeniuslabs.org. Visitors to the house have raved about its patterns and how it adds a pleasant accent to our family den.

I have several Fibonacci1024 section LED PCBs, but not a full set. I will likely not be ordering more until the current tariff insanity stops (if ever), so I'm engraving & cutting acrylic to make them standalone pieces. Let me know if you're interested.

This is the beautiful carcass left behind after laser cutting the Voronoi grid for the 320mm Fibonacci512.
