This little motion-sensitive 75mm Fibonacci256 prototype might be my favorite new thing I've made in a while. This was totally inspired by @starduststorm.art's brilliant "The Hexagon" which you should definitely go buy instead of waiting for me to make more of these. 😁

With the INDX 4-tool conversion kit for my @prusa3d.com CORE One scheduled for delivery today, it is once again time to disassemble my perfectly functional 3D printer. 😁
This will be the fourth time I've upgraded this printer, which I assembled as an i3 MK3S+ kit five years ago.

Perlin noise flow field pattern. Particles follow a noise flow field that slowly evolves over time. The flow field has a strong upward bias. Each particle leaves a fading trail drawn from the currently selected color palette. Particles respawn at the bottom when they drift off-screen or age out.

I'm revisiting "Sol v2". I tore it down, rewired the 1,628 pixels into eight parallel channels, and went from 20 to 72 FPS. 😁
