| Phyllotaxis: An audio-reactive LED display(jagi.studio) | |

tl;dr: A developer built a sunflower-inspired LED display by generating a phyllotaxis pattern in code, Voronoi-tessellating it, and 3D printing cell walls to hold 89 addressable LEDs behind translucent mulberry paper. An STM32 (later ESP32) drives shader-style animations and runs FFT-based audio analysis via an I2S mic for real-time reactivity. A second version replaced the 3D-printed backplate with modular PCBs in 5-fold symmetry, now installed at Recurse Center with a web interface for uploading custom sketches. | |
