Where mathematics meets organic beauty
Phyllotaxis is the arrangement of leaves, seeds, or florets around a stem or center. This spiral pattern follows the Fibonacci sequence and the golden angle (≈137.5°), maximizing exposure to sunlight and packing efficiency.
The golden ratio in nature
Sound captured via microphone or audio interface
FFT processing extracts frequency bands and amplitude
Audio data mapped to phyllotaxis spiral coordinates
Dynamic color and brightness drive the LED array
Technology that brings math to life
Low-latency audio analysis for instant visual response
LEDs arranged in mathematically precise phyllotaxis pattern
Frequency bands mapped to hue, saturation, and brightness
Adjustable sensitivity and visual parameters
Efficient embedded processing on hardware platform
Mesmerizing display that reacts to any audio source
