&co Rorschach Ink Blot Visualizer

 &coRocharch Visualizer listens. Make a sound — any sound — and watch a Rorschach-style inkblot grow in real time, shaped by your voice, your music, your room.

Stop. The shape retraces itself and dissolves. Make another sound. Get a completely different shape.

No two sessions are the same.

 &coRocharch Visualizer is a browser-based generative art tool that turns audio into living symmetrical forms. It uses your microphone or system audio (Spotify, YouTube, anything playing on your device) to grow an organic inkblot — one arm, lobe, and satellite dot at a time.

Bass frequencies swell the core. Mid-range frequencies push out the wings. High frequencies spike the edges. Interior dots fill the negative space as the shape matures, and scattered satellite blobs drift outward as the growth reaches its peak.

Every inkblot is built from a randomly generated "DNA" — a unique set of arm positions, widths, and heights that determines the personality of the shape. Clear the canvas, and a new DNA is generated. No two sessions look alike.

SYSTEM AUDIO NOTE

To react to music playing on your device, click "system audio" — a screen-share prompt appears. Tick "Share system audio" before confirming. No video is captured or stored — only the audio stream is used, and it never leaves your machine.

SLOW COMPUTERS WELCOME

On older or slower hardware, Ink Blot runs at a natural pace that has its own quiet beauty — like watching ink spread through paper. The speed slider lets you dial in the exact feel you want, from meditative to reactive.
