Geiss
Biology-inspired diffusion fields that evolve with every beat.
Reaction diffusion simulates two chemical species competing across a surface, and Geiss wired it to your audio. Beats trigger new reaction zones; the bass concentrates pigment; high frequencies diffuse the edges into lace. The surface looks organic because the math behind it is alive.
The core fractal lane. Dense recursion, spiral pull, reaction-diffusion, and the signatures that make the whole medium feel unmistakably MilkDrop. These presets are the reason people have been running visualizers for two decades.
Recursive tunnels, artifacts, and deep mathematical pull.
Upload any audio
Drag in a local file, connect a mic, stream a radio URL, or use one of the included sample tracks.
Real-time analysis
The Web Audio API analyses frequency content, amplitude, and transients at up to 60 fps, all without leaving your tab.
Shader renders the result
Butterchurn translates that data into GLSL shader parameters. Geiss - Reaction Diffusion 3 maps those parameters into its own visual language.
